Party Systems and Patterns of Government in Western Democracies

J. BLONDEL University of Essex

The study of patterns of government in Western democracies has been greatly improved by the work devoted recently to the smaller democracies. Although it

may be premature at this stage to expect to obtain firm conclusions and although one should probably only try to draw a sketch of the main lines of a comparative analysis, it is at least possible to go beyond some of the classic typologies which tended to contrast, for instance, the British to the American system of govern- ment or the Anglo-Saxon to the French.'

An analysis of patterns of government in Western democracies must begin by an attempt to circumscribe and operationalize the characteristic features of the

"population" under consideration. This population has many common institu- tional and behavioural traits; its socio-economic structures are also very similar, at least by comparison with the rest of the world. We are therefore able to control for certain variations and, consequently, to come to more definite conclusions about the influence of others. But at least three types of difficulties remain.

First, the characteristic features of the political systems of these countries are almost certainly among the most awkward to summarize or grasp because of their complexity. Second, the most advanced method which we have at our

disposal in comparative government, structural-functionalism, is only of limited

*Paper read at the Seventh World Congress of the International Political Science Associa- tion at Brussels, September 1967. 1Although the literature on parties is vast, the number of works specifically devoted to the study of party systems is relatively small, at least in relation to systems of more than one party. In this context, practically all the discussions have been related to the contrast between two-party systems and other systems, as is for instance the case in M. Duverger's Political Parties (Paris, 1951). The same applies to S. Neumann's Modern Political Parties (Chicago, 1956). More recently, distinctions have been made between stable and less stable multi- party systems, usually on the basis of contrasts between Scandinavian countries and the Netherlands, on the one hand, and France on the other. R. A. Dahl's Political Opposition in Western Democracies (New Haven, 1966) considers this problem in relation to each country and in a general fashion, but the precise characteristics of the party systems of the various countries of the group are not specifically mentioned. The forthcoming study of the Smaller European Democracies will also help to fill the gap in this field. Interest in the question was shown at the 1967 International Political Science Association Congress, where a number of the papers (including the present study) were related to the close examination of types of party systems, in particular those of A. Lipjhart, "Typologies of Democratic Systems," and G. Sartori, "Parties and Party Systems: A Theoretical Frame- work."

The present article would not have been written but for the suggestion of H. Daalder whose interest in the subject has been long-standing and whom the author wishes to thank particularly. Finally, the most comprehensive general review of types of party systems in both Western and developing areas is that of S. M. Lipset, "Political Cleavages in 'Developed' and 'Emerging' Polities," in E. Allardt & Y. Littunen, eds., Cleavages, Ideologies and Party Systems (Helsinki, 1964).

Systemes de partis et types de structures gouvernementales dans les democraties occidentales

11 existe quatre types de systemes de partis dans les democraties occidentales, le systeme de deux partis, le systeme de deux partis et demi, le systeme multi-parti avec parti dominant, et le systeme multi-parti sans parti dominant. Presque toutes les democraties occidentales ont conserve le meme type de parti tout au long de l'apres- guerre. Chaque type a ses caracteristiques propres qui constituent autant de meca- nismes automatiques d'equilibre. Les types de structures gouvernementales peuvent etre definies par l'intermediaire des forces politiques qui se trouvent representees au gouvernement, soit conjointement, soit successivement; ils peuvent egalement etre definis en termes de stabilite. Au cours de l'apres-guerre, le systeme multi-parti avec parti dominant semble avoir donne naissance a la forme de representation la moins equitable; la stabilite gouvernementale parait dependre de la presence d'un seul, et non de deux partis importants.

usefulness when we try to apply it to the detailed analysis of patterns of govern- ment. Functions are broad and consequently somewhat vague, whether on the input or the output side. We shall therefore consider here certain concrete variables and remain close to the complex realities of political structures and processes in Western democracies, although these are of less general application than the variables used in structural-functionalism. Third, no over-all yardstick with which to compare the Western countries has been clearly defined. Cross- national analysis has typically been developed around the ideas of stability and

development. By concentrating on nineteen developed countries which are also

essentially stable, although a few exceptions can be found, we are precluding ourselves from using either of the accepted thermometers. Admittedly, if our instruments were more refined, we could consider stability and/or development as continuums and we might be able to measure, for instance, the relative stability of Iceland and Belgium. But, except in a few cases, such as France, stability cannot be measured directly in the context of Western democracies.

We shall therefore concentrate in this paper on manifestations of political life which appear to be characteristic of Western democracies and which, surprisingly enough, have not received up to now the attention they might have justified. Among these manifestations, the two most important are probably the types of party systems and the types of governmental structures. Their examination in itself should reveal the existence (or absence) of patterns; these in turn should indicate whether certain forms of governmental or political behaviour are more likely or less likely to occur than others. The consideration of the relationship between party systems and governmental structures should also reveal whether certain regularities can be expected or whether the distribution of each of the variables is random in relation to the others. While such an analysis is clearly not of direct relevance to a general study of comparative government extending beyond Western democracies, there may be some indirect pay-off to the extent that it might be possible to assess the probability of certain types of developments in countries whose political system is similar to, though none the less distinct from, that of Western democracies.

Party systems and patterns of government: the selection of variables for analysis of relationship Western party systems have attracted attention for several decades, but in only one respect, that of the possible influence of electoral systems on the number of

parties, has there been any systematic examination of a possible relationship.2 Little consideration has been given to the possible effect of party systems on the

type and characteristics of the governmental structure and of governmental decision-making. It is generally assumed that two-party systems are concomitant with relatively stable governments: yet even this proposition has not been directly confronted with the available evidence. No other proposition of this or any similar type has been subjected to an empirical analysis, nor have hypotheses even been formulated.

Endeavours to generalize in this field are admittedly hampered by a number of difficulties. One of these is structural: even when the smaller democracies are included the number of countries is relatively small and the time span short. To the fifteen democracies of northern and western Europe3 must be added four

Anglo-Saxon countries outside Europe, namely the United States, Canada, Australia, and New Zealand. The homogeneity of the universe diminishes if one moves outside this group of countries.

A second type of difficulty arises from the unavailability of certain types of data directly relevant to the analysis of governmental patterns. Party systems are

generally well-known: the size of parties and their general ideology or broad

policy standpoints are usually easy to obtain. But much less is available about

governmental systems. We have practically no information, at least for most countries, about any but the most formal arrangements. We do not know whether governmental structures are really collective or oligarchical or monarchi- cal. We have very little information on patterns of internal decision-making.

Nor is the "effectiveness" of the government easy to measure on the basis of available data. Clearly the best test of governmental achievement-that of the amount of "important" legislation passed by the legislature, with or without amendment-would suppose a detailed knowledge of patterns of legislative behaviour in relation to outputs, which are, at this stage, unfortunately only available for a limited number of countries and, in many of these cases, only for short periods. One has therefore to rely, as we shall do in this paper, on much less satisfactory indicators, such as the stability of governments, a criterion which cannot in any case be applied to the two countries in the group, the United States and Switzerland, which do not have a parliamentary system.

Problems of operationalization have been the third major type of difficulty encountered in comparative government. The notion of party system has remained somewhat loose and the notion of pattern of government even more

2The literature on the relationship between electoral systems and party systems is vast, the main works being those of F. A. Hermens, Democracy or Anarchy? (Notre Dame, 1941), Duverger, Political Parties, and L'influence des systemes electoraux sur la vie politique (Paris, 1950) and E. Lakeman & J. D. Lambert, Voting in Democracies (London, 1955). See also C. Leys, "Models, Theories and the Theory of Political Parties," Political Studies, VII, no. 2. :'The United Kingdom, Ireland, France, Germany, Italy, Belgium, the Netherlands, Luxem- burg, Iceland, Norway, Sweden, Finland, Denmark, Switzerland, and Austria.

nebulous. Yet it is possible to acquire at least some information in relation to two

specific governmental characteristics, stability and extent of coalition-building. Neither of these characteristics will reveal more than part of the aspects of

governmental life which are of importance. But, as long as other indicators are not available, the study of the stability of governments and of coalition formation and duration will give some information on various aspects of patterns of

government. In particular, it is usually assumed that stability leads to efficiency and ensures support for the system, while governmental instability will foster alienation and will be characterized by inefficiency. The study of types and extent of coalition will provide information on the breadth of the support for

government, on its representativeness in party terms, at any given point in time. Thus, although more work is required to ascertain whether governmental stability or coalition government are indeed closely related to support for the regime, executive efficiency, or representativeness of government, it seems reasonable to assume that there is a relationship and it becomes significant to consider in some detail the patterns which emerge from the analysis of the indicators which we have at present at our disposal.

We propose to examine in this paper both whether concepts of party systems and of governmental patterns can thus be operationalized and, if so, whether certain tentative conclusions can be drawn about the relationship between the variables. We shall thus begin by attempting to see whether the nineteen coun- tries of western Europe and of the Anglo-Saxon world can be grouped, with reference to their party system, in a small number of categories in which there are common positive characteristics.

If patterns of party systems exist, it will also be possible to examine to what extent these appear to be related with certain forms of government. Is it clear that coalition government or unstable government or less party-representative government is more likely to occur in countries which have certain types of party systems? Are coalition governments less likely to be stable, while more likely to be representative of the shades of opinion in the country? Obviously, our

knowledge of patterns of government will be increased when we can introduce variables relating to prime-ministerial government or to the power of the govern- ment in connection with legislation. But some of the variables which can be

operationalized may already give some idea of the possible influence of party systems on patterns of government.

PARTY SYSTEMS

If undertaken on a world basis, the analysis of party systems would require a consideration of the number of parties, of their strength, of their place on the

ideological spectrum, of the nature of their support, and of their organization and type of leadership. In the context of Western liberal democracies, it is

possible to limit the analysis to the first three of these characteristics. With

very few exceptions, Western parties can be deemed to be of the "legitimate" mass type and to have a regularized system of leadership selection. Charismatic

leadership is exceptional and, at the other extreme, Communist parties are

becoming increasingly similar to other parties. Western parties appeal nationally to the electorate by trying to put across a general image; differences are more to

Western Democracies 183

Page 6: Blondel Party Systems

be found in the type of image than in the structural characteristics of the

organization.

1. Number of parties in the system Two-party systems are rarely defined operationally. Yet, among Western democracies, four groups are clearly discernible (see Table I). Five countries

give on average more than 90 per cent of their votes to the two major parties.

TABLE I

AVERAGE TWO-PARTY VOTE, 1945-66 (percentage)

United States 99 Denmark 66 New Zealand 95 Sweden 66 Australia 93 Norway 64 United Kingdom 92 Italy 64 Austria 89 Iceland 62

Holland 62 West Germany 80 Luxemburg 80 Switzerland 50 Canada 79 France 50 Belgium 78 Finland 49 Eire 75

Second, five countries give between 75 and 80 per cent of their votes to the two

major parties (though Belgium fell markedly below this level at the last election). In six countries, the two major parties obtain about two-thirds of the votes

(though Holland is somewhat different, as we shall see). Finally, three countries

give about half their votes to the two major parties, though, for the last two elections, France would have to be moved from the fourth to the third category: but as the French situation may well alter again after the end of the de Gaulle

era, it is probably more realistic to draw conclusions from the average of the whole post-war period than merely from developments in the 1960s.

Countries belonging to the first group can be defined as two-party systems, though there is some ambiguity in the cases of Australia and Austria; in both these countries some governments depended for their constitution or maintenance on the support of more than one party. The five countries of the second group constitute the three-party systems, Germany having arrived at this status as a result of the operation of the electoral system as well as of the Adenauer tactics. The nine countries of the last two groups are the genuine multi-party systems, in which four, five, or even six parties play a significant part in the political process.

2. Strength of parties Little has to be said about countries of the first group, in which 90 per cent or more of the electors vote for, and 90 per cent or more of the seats are distributed between, the two major parties. It is interesting to note that discrepancies in

strength between the two major parties are remarkably small, at least if averaged over the post-war period. While it could in theory be the case that one party might be permanently much larger than the other, no two-party system (i.e., no

system in which the two parties obtain 89 per cent of the votes) gives to the

larger of the two parties a permanent premium of over 10 per cent of its own electorate. Despite differences in social structure, for instance, between the

184 J. BLONDEL

Page 7: Blondel Party Systems

United States, the United Kingdom, and Austria, the electorate distributes its

preferences fairly evenly between the two parties. Although it cannot be stated with assurance that such a situation cannot exist in any type of social system (there are indeed examples of uneven distribution of party support among two-

party systems outside Western democracies), it seems possible to hypothesize, in the absence of contrary evidence, that, in Western democracies, two-party systems show a tendency towards a relative equilibrium between the two parties.

Countries in the three-party system group also share several characteristics.

Average disparity between the two major parties 1.6 10.5

First, disparities in strength between the two larger parties are generally much

greater than among countries in the first group. They seem structural in that the

swing of the pendulum does not, as among countries of the first group, diminish the gap, even if one considers a fairly long period: the average percentage point difference between the two major parties among the five countries of the first

group is only 1.6 if all post-war elections are taken into account; it is 10.5 in countries of the second group (excluding Luxemburg where data for all elections were not available). The often stressed phenomenon of the German SPD, which has not been able to achieve equality of strength with the CDU, is thus a general phenomenon among countries of this group. It can therefore be stated that in countries in which about 80 per cent of the votes go to two parties the distribu- tion of the support tends to be uneven.

Three-party systems also have another, and converse, characteristic. They all have two major parties and a much smaller third party. While it would seem

theoretically possible for three-party systems to exist in which all three significant parties were of about equal size, there are in fact no three-party systems of this kind among Western democracies: all the three-party systems are in the second

group; all systems of the third group have more than three significant parties. It can thus be stated that, while theoretically possible, a genuine three-party system is not a likely type of system among Western democracies: countries of the second group should therefore be more strictly labelled as "two-and-a-half-party systems." It may indeed be permissible to add, after considering the evolution of

party systems, particularly in the early part of the twentieth century, that

genuine three-party systems do not normally occur because they are essentially transitional, thus unstable, forms of party systems.

The situation arising out of the 1965 Belgian election was thus of particular

Western Democracies 185

Page 8: Blondel Party Systems

interest, since the upsurge of the Liberal party and the decline of the two major parties was such that Belgium appeared to have moved into the exceptional and

seemingly transitional position of a "genuine" three-party system. If the proposi- tion advanced earlier is correct, it would seem that in the next few years Belgium will move to one of three types of further changes. The Liberals could return to their "normal" position of small party; they could displace one of the two major parties (an unprecedented development in Western Europe since all the move- ments happened in the other direction); a split could occur among the supporters of one or both of the major parties and Belgium might move from the second

group of countries (two-and-a-half-party systems) to the third or fourth (multi- party systems). From the experience of other Western democracies the first and third of these three outcomes appears more probable than the maintenance of a

genuine three-party system. We included Holland among the countries which constituted the third group,

composed of those countries in which the two largest parties obtained about two-thirds of the votes of the electorate. But if we consider the relative strength of the two major parties, the five other countries of the group differ markedly from Holland, in that they have one very large party, which might be defined as dominant as it obtains about 40 per cent of the electorate and generally gains about twice as many votes as the second party. In fact, in both Norway and Sweden, the mechanics of the electoral system have sometimes enabled this dominant party to obtain the absolute majority of seats in the Chamber. But these countries are at the same time multi-party systems as they all have four or five significant (and often well-structured) parties playing a crucial role in the

operation of the political system. Four of the five Scandinavian countries are included in this group (the fifth being Italy), though in Iceland the dominant

party is not the Socialist but the Conservative (Independence) party. The Fifth

Republic, at least under de Gaulle, appears to be moving towards this pattern of party system, though the characteristics of the Gaullist party are such that it seems unreasonable to predict that the present party configuration is likely to survive de Gaulle. Thus, alongside two-party systems and two-and-a-half-party systems, the third group should be defined, not so much as a multi-party system in which two parties obtain about two-thirds of the votes of the electorate, but as a multi-party system with a dominant party which obtains about two-fifths and less than half of the votes.

Finally, the last four countries (if Holland is included and France maintained in the group in the view of the past and possible future performance of that country) constitute the "genuine" multi-party systems: they have no dominant

body and indeed seem to show a pattern of political behaviour in which three or four parties are equally well placed to combine or form coalitions. Recent elec- toral movements in Holland appear to bring that country gradually nearer towards this model: the slow decline of the Labour party and the patterns of governmental formation have tended to conform fairly closely to those which have been customary of Finland.

3. Ideological spectrum and party strength Western democracies can therefore be divided into four groups, if both numbers and strengths are taken into account: five are in the two-party system group, five

186 J. BLONDEL

Page 9: Blondel Party Systems

in the two-and-a-half-party system group, five in the group of multi-party systems with dominant party, and four in the group of multi-party systems without dominant party. But the party system can only wholly be defined if we take into account the position of parties on the ideological spectrum, particularly when the system does not have a "symmetrical" character.

Even in Western democracies, parties are difficult to categorize accurately. The United States and Eire always had parties which do not fit in any easily recognizable typology. The French Gaullists are not ordinary Conservatives, though they may have to be lumped with Conservatives for comparative pur- poses. The other multi-party system countries all have parties of a somewhat

peculiar type, such as the two Conservative parties in Holland, the Swedish party in Finland, and the party of the Peasants, Artisans and Bourgeois in Switzerland. In all these cases, certain rough approximations have had to be made.

Table III shows the panorama of party strengths within the ideological spectrum. Group 1, except for the United States, is fairly homogeneous: the four other countries in the group have a large Socialist party and a large Conservative

or Christian party, together with a small other group, whose position in the centre is perhaps sometimes problematic. Countries of group 2 have two types of

party systems: Belgium, Germany, and Luxemburg resemble countries of

group 1, except that the centre party is stronger and, as we noted earlier, this increased strength is mainly at the expense of one only of the two major parties (in fact the Socialist party). The other two countries of the group (Canada and Eire) are different: the small party is not the centre, but the left-wing, party and, probably not quite accidentally, the right-wing party is not Christian but Con- servative. In the early part of the twentieth century, it would probably have been

argued that both these countries were still in a transitional stage: Canada has a

party system not unlike that of Britain in 1906. But it must by now be recognized both that the two-and-a-half-party system is stable (Belgium and Germany have had for long periods the British party system of the 1920s and do not appear to move further towards a two-party system) and that the two-and-a-half-party system is stable even if the left-wing party is the small party. Neither the Irish Labour party nor the Canadian NDP appear to be in a position to overtake the centre party in the near future: their position of small party seems stable. The reasons for the stability of the Canadian model of two-and-a-half-party system are probably to be found along lines similar to those which account for the

stability of the American parties, which have remained in existence despite earlier predictions to the contrary.

Two types, and not more than two types, of multi-party systems with a dominant party can be found. Three Scandinavian countries have a dominant Socialist party; Iceland and Italy have a dominant Conservative or Christian

party. In the latter two cases, we encounter for the first time countries with a

really large Communist party. In Iceland and Italy (as in Finland and even France) the Communist party remained fairly stable throughout the whole

period; the Socialist party is therefore correspondingly weak and the left is divided; as is well known, the converse occurs in Norway, Denmark, and Sweden. In these three countries, though the agrarian party is not placed symmetrically in relation to the Communists on the political spectrum, it probably plays the same divisive part. The absence of religious divisions might have led one to expect the three Scandinavian countries which do not have a large Communist party to have

two-and-a-half-party systems, but the apparent feelings of identity of the agri- cultural community have created permanent cleavages on the right which have

produced a party system in many ways "symmetrical" to that of Iceland and

Italy. Countries of the fourth group have no dominant party: party strengths are

therefore fairly evenly spread across the ideological spectrum, though Holland and Switzerland, with weak Communist parties, display somewhat less spread than France and Finland. This latter country combines the splintering charac- teristics of left and right of the Scandinavian countries: the divisions of Iceland are superimposed on those of Sweden.

There are thus six types of party systems in Western democracies. At one extreme are the broadly based parties of the two-party system countries: the United States is the most perfect case of this type, but four other countries

closely approximate this model and they only diverge inasmuch as they have a

188 J. BLONDEL

Page 11: Blondel Party Systems

small centre party and are divided ideologically between conservatives and socialists. At the other extreme, the votes of the electors are spread fairly evenly, in groups of not much more than 25 per cent and in many cases much less than 25 per cent over the whole ideological spectrum, as in Holland, Switzerland, France, and Finland. Between these two poles, one finds four types of party systems: five countries have two-and-a-half-party systems: among them, three have a smaller centre party, while the other two have a smaller left-wing party. The five remaining countries are multi-party systems with a dominant party, three of them having a dominant socialist party opposed by a divided right, largely because of the presence of an agrarian sentiment in the countries con- cerned, while the other two have a strong right-wing party opposed by a divided left, largely because of the presence of a substantial Communist party.

A number of types of party systems, which are theoretically possible, do not

appear to exist. There are no three-party systems, as we saw; there are no "unbalanced" two-party systems. There are, moreover, only two existing ideo-

logical models of two-and-a-half-party systems out of the three which might have existed. Dominant parties in multi-party systems tend to be of the right or left, not of the centre. Patterns of party systems in Western democracies are thus limited in number. There are discrete points at which party systems are to be found: not only social structures but balance and equilibrium have surely to be taken into account in an analysis of the real world distribution of Western party systems.

4. The dynamics of party systems in the post-war period Party systems are also very stable. Germany is the one clear case of shift from one group to another during the post-war period. In 1949 Germany would have had to be classified in the fourth group, its party system resembling in many ways that of Holland; by 1957, the German party system was similar to that of

Belgium or Luxemburg. It is perhaps not altogether surprising that a country which was so fundamentally reconstructed politically (and whose territory strikingly diminished after the war) should have experienced such a transforma- tion in its party system. All the other cases are doubtful. France, as we noted, is

apparently moving now from the fourth to the third group, but it seems difficult to predict that the change will be permanent. In two other cases, Belgium and Austria, future moves are possible, though they are still far from certain: while Austria may move towards a two-and-a-half-party system if the third party is more seriously taken into account as a result of the break-up of the Christian- Socialist coalition, the electoral basis for the change is still not apparent. Belgium may become a multi-party system if the growth of the Liberals encourages splits among the major parties, but a more likely development still seems to be the return to a normal two-and-a-half-party system. Party systems in Western democracies therefore remain in existence for very long periods: they can be categorized and grouped with a considerable degree of accuracy. That this should be the case may be a sign of over-all political stability and a consequence of the developed character of these political systems: cross-national studies extending beyond Western democracies might indeed show that party systems elsewhere are neither as "clear" nor as stable. There seems therefore a strong argument for

Western Democracies 189

Page 12: Blondel Party Systems

examining whether these patterns of party systems are reflected in the govern- mental structures of the countries concerned.

GOVERNMENTAL PATTERNS: STABILITY AND STRUCTURE OF GOVERNMENT

1. Duration of governments The duration of governments can, of course, be analysed only for the seventeen countries in which the system of government is parliamentary (it does not seem necessary to exclude France from the group, but Switzerland and the United States certainly have to be). For these seventeen countries, an index of average duration of governments was therefore constructed: as such an index has to rest on an operational definition of government, it is not possible to avoid drawing some arbitrary boundaries. For the purposes of the present analysis, any administration was considered as one government which fulfilled two conditions: that of being headed by the same prime minister and that of relying on the support of the same party or parties in the Chamber. No other operational definition appeared acceptable. A more restrictive definition which would have included reshuffles would have had in order to be truly operational, to include many minor changes and would have therefore made us consider as ministerial crises changes of personnel which appear routine to observers and are in no sense seen as crises. There are major reshuffles, admittedly; in some cases, as in Britain in 1962, the scale of the changes is such that it can be, and might elsewhere have been deemed to be, a ministerial crisis, but it did not seem possible to define operationally, at this stage, a "reshuffle bar,"4 above which reshuffles could have been equated to ministerial crises. Conversely, while a change in the basis of party support for the government surely constitutes a change of govern- ment, a change of prime minister may be due to accidental causes, such as ill-health or death: the number of crises may thus be somewhat overestimated in some countries (as might indeed be the case for Denmark). But changes of prime ministers, even with the same party support, are normally an indication that a governmental crisis has taken place: the French and Italian governmental sys- tems would become surprisingly stable if only changes in party support were taken into account.

The average for the seventeen countries ranges from five to seven years in Sweden and Australia to less than a year in Italy, Finland, and France (despite the new stability of the Fifth Republic) (Table IV). Countries can be divided into four well-defined groups: in four countries, governments lasted five years or more (Australia, Sweden, New Zealand, and Canada); in a second group of four countries, governments lasted an average of little more than three years (Britain, Eire, Germany, and Norway); in the third group of five, governments lasted somewhat over two years (Austria, Luxemburg, Iceland, Denmark, and Hol- land); and in four countries, governments were in office on average for about a year (Belgium, Finland, Italy, and France). Thus governmental stability is much lower everywhere than is intuitively felt: a British prime minister is unlikely to remain more than three or four years in office; Dutch governments are not only 4Such a reshuffle bar could be defined by taking into account the number and importance of ministerial posts which change hands at a given point in time or over a very short period.

difficult to form-they are not likely to remain in being for very long. Admittedly, both these cases can be "explained" by a series of accidents. Dutch governments were stable in the first decade of the post-war period when Mr. Beel and Mr. Drees dominated the political scene; it may be that the present period of

instability will be followed by a return to greater governmental duration, though the results of recent general elections do not seem to give much support for such a conclusion. In Britain, Churchill's age, Eden's Suez policy and subsequent bad health, and Macmillan's illness appear to account on the superficial level for

fairly frequent governmental changes; but it is interesting to note that "accidents" of this kind should take place relatively often; their repetition does throw some doubt on the accidental theory itself. In fact, prime ministers, like ministers, are

frequently replaced. Parliamentary regimes are in this sense more unstable than a presidential system like that of the United States. Few countries keep govern- ments with the same political base and the same head for as many as four years (one US presidential term) and only the Australian, Canadian, and Swedish governments show the same stability as that of the United States executive. As a result, it is perhaps ironical to note that the difference between a stable and an unstable governmental pattern remains very narrow: the borderline appears to be somewhere between one and two years. Expectations of public opinion and politicians may be different, and governmental efficiency may be greater on the

upper side of the line: but it remains true that parliamentary governments are rarely very stable and that stable parliamentary regimes change their government fairly often.

2. The political structure of governments The duration of governments is an indicator of the stability of the system; it can also be taken to constitute an indicator of the potential efficiency of governments. By studying the political complexion of governments over a relatively long period, one can measure, on the other hand, the representativeness of the executive. If different political groups have a share in the government over a given period, the system would appear to be representative. It would also seem reasonable to assume that, the more a party shares in government, the more it is able to carry out its policies. Admittedly, parties may be frustrated by the action of others which act consistently more cleverly; some parties may also tend to act not so

191

Page 14: Blondel Party Systems

much in accordance with their own stated policies but on the basis of circum- stances and in order to win over opponents without whose support the govern- ment may not be able to remain in office. But it can at least be assumed that, over a period, the relative amount of political astuteness is reasonably well

spread and the relative degree of policy implementation is broadly similar. While such an assumption might not be valid if Western and non-Western countries were compared, it appears acceptable, at least as a working hypothesis, among Western democracies, where the conditions of the political game are broadly similar.

The relative participation of parties in government can fruitfully be viewed from two perspectives. First, it is interesting to relate the participation of parties in government to their share of the national vote. Are certain significant groups of electors constantly under-represented in the executive circles? Second, the

analysis of the relative participation of parties in the government makes it pos- sible to compare the effect of two types of governmental arrangements practised in Western democracies, the one-party government system and the coalition

system. There are, in fact, at least two types of coalitions: the small and the grand

coalition, the latter having sometimes been known as the "Austrian solution." The grand coalition is rarely imposed upon politicians by the circumstances of

party representation in parliament: it is more often than not the product of a determined and conscious political philosophy as a result of which a high premium is given to the sharing of power and a rather low value to clear-cut decisions.

The Austrian solution (now abandoned by Austria, of course) has been

widely practised among Western democracies. In Table V, countries have been ranked on the basis of one point per year where there was no coalition, two

points per year of small coalition, and four points per year of grand coalition.5

A majority of Western countries receive at least forty points: they have therefore at least occasionally practised the grand coalition and only Anglo-Saxon and some Scandinavian countries have not done so.

Do coalitions enable the various political parties to be represented more fairly than single-party government? In principle, the idea of coalition government is

5For the purpose of the allocation of points, grand coalition is defined as one in which parties representing jointly over 75 per cent of the electorate take part.

192 J. BLONDEL

Page 15: Blondel Party Systems

that of simultaneous representation of the various forces (or some of the political forces). Single-party government has to be based on a different unwritten rule, that of "successive" representation. But such a successive representation can be fair representation only if a "divine hand" makes the pendulum swing regularly. Conversely, coalition government, unless it takes the form of a permanent grand coalition, can equally bring about distortions, though these are less likely to be caused by accidents of electoral success than by conscious (or at least half- conscious) patterns of behaviour of the politicians.

The operation of the divine hand can only be examined if countries which

practise single-party government are considered over a long period. It seems

equally reasonable to consider the operation of coalitions over a longish period, as the prejudices and biases of politicians are apt to change after a decade and certain ostracisms may tend to be less marked. An index was therefore con- structed for Western democracies based on the twenty-year period starting in 1946. It was assumed that if serious distortions did still appear when considering such a long time span, it could be claimed with assurance that, on the whole, fair representation was not normally achieved.

Certain features of an index of this kind have to remain somewhat arbitrary, as it is based on the attribution of a share of power or at least of representation to parties in a coalition. In the formulation used in this paper, 10 points per year are attributed to each country. When the government is wholly composed of members of the same party, the party is allocated all 10 points: thus, as the British Conservative party was in office alone for thirteen years of the period 1946-65, it receives 130 points, while the Labour party, in office for the other seven, received 70 points. It therefore follows that Labour had a 35 per cent share in the government during the whole of the period while the Conservatives had a share of 65 per cent. When, on the other hand, the government consists of a coalition, one basis for allocation might be the ratio of ministers of each

party to the total number of ministers (though perhaps an extra point should be

given to the party which has the prime minister). As data on all governments could not easily be obtained, the calculations used in this paper are based not so

strictly on the percentage of ministers of each party as on a rougher division

corresponding broadly to the relative strength of the various parties in Parlia- ment. Thus, in the Austrian case, 100 points were allocated to each of the two

parties for the whole of the period, since they were in constant partnership up to 1966. Admittedly, the People's party should probably have been allocated a few more points than the Socialists, since they were more often than not the senior partners of the coalition; but the difference would be small-probably not more than 105 or at the most 110 for the People's party. Thus it seems that, while the British Labour party obtained, during the period, about one-third of the total British government's share, the Austrian Socialists, who obtained generally about the same percentage of votes cast as the British Labour party, obtained a percentage of participation of about 50 per cent.

Calculations for most countries were much less simple than for Austria or Britain and therefore somewhat more arbitrary: they are reproduced in Table VI on a percentage basis (the details for the "points year" calculation for each of the countries concerned are given in the Appendix). Even if exact percentages of ministers had been taken into account, it would have been difficult to know

precisely how much each of them had participated in the government. Points

give orders of magnitude: the Dutch Liberals may perhaps have had a share of about 8-12 per cent in government: it is unlikely that their participation was as high as 20 or as low as 2 per cent.

The main and not altogether surprising general conclusion is that left-wing participation has been markedly low, except in three Scandinavian countries and in Austria. What is also clear, however, is that differences in electoral strength appear to explain very little: the type of governmental arrangement (single-party government or coalition) and the type of party system need to be considered at least as carefully as the electoral strength of parties.

Patterns of government, institutions and party systems

THE PARTICIPATION OF POLITICAL PARTIES IN GOVERNMENT

We saw that governments in Western democracies have experimented with three main types of arrangements: one-party, small coalition, grand coalition. But the three types of governmental arrangements are not equally embedded in the

political culture of a particular country. While party government is an unwritten rule of government in Anglo-Saxon countries, there is less stability and "agree- ment" about patterns of governmental arrangements on the Continent.

By using the ranking and the "points year" system, however, one can examine whether the governments of countries which have tended to practise the coalition idea have in fact represented the various forces in the nation better than the

governments of countries which have normally been constituted by single parties. Table VII shows that the countries which have practised the grand coalition

194

Page 17: Blondel Party Systems

tend most regularly to have the best party representation, that one-part govern- ments tend to have ensured a moderate level of representation, and that the

greatest distortions are to be found among those countries which have practised the small coalition idea normally or only intermittently. It can therefore be stated, at least in the first instance, that grand coalitions are more likely to ensure fair representation of parties in government that one-party government, but that

one-party government ensures normally a fairer representation than the small or intermittent coalition.

This finding needs to be qualified, however, by relating the degree of repre- sentation to the type of party system. Distortions in representation vary con-

siderably within each type of party system and, in three cases out of four, the

average distortion is about the same. But the average distortion is much higher in the fourth type of party system, that of the multi-party system with a dominant

party (see Table VIII). Thus two-party systems are not more likely to ensure

representation than two-and-a-half- or multi-party systems. Perhaps because twp-and-a-half-party systems are more likely to provide a

ground for grand coalitions than two-party systems, these systems tend to ensure as good a representation as two-party systems. In both groups of countries, there

*The distortion in representation in government is calculated on the basis of the difference between party support in the country and party representation in government

Western Democracies 195

Page 18: Blondel Party Systems

is one instance of a high distortion rate. In Australia, the divine hand did not

operate to ensure a swing of the pendulum; in Germany, Adenauer's efforts to work a party government have prevented for a time (but only for a time) the

government of Bonn from moving towards a grand coalition and from joining Belgium and Luxemburg in the direction of a low distortion rate.

This finding can be generalized by introducing the notion of balance and

particularly of balance between right and left. We noticed that in two-party systems the two parties tended to be evenly balanced and that in two-and-a-half-

party systems there was some unbalance between the two major parties, but that it was small. At the other extreme, multi-party systems without a dominant party are also balanced, though the distinction between right and left is less clear in these countries: the balance which prevails in this type of party system appears to be that of the political oligopoly. Hence a large number of combinations; hence also, particularly where communists are not strong, the impression that

representation can be effective, obviously on a coalition basis, but between all

parties. There is a premium given to the centre parties, around which most coalitions tend to be formed: this premium is largest in Finland (Agrarians), but it applies to the Dutch Catholic party, the French Radicals and MRP, and to the Swiss Radicals.

The multi-party system with a dominant party is, on the contrary, structurally unbalanced. The dominant party is in the position of a large firm faced with a number of much smaller competitors: it can manipulate the situation much more

easily than any party in any other of the party systems. Indeed, one can list in broad terms the conditions which will maximize the dominance of the large party. First, it must "appear" to be dominant in terms both of votes (40 per cent of the electorate seems to constitute a minimum) and of strength in relation to the second party (about twice as many votes). The nearer the dominant party comes to receiving 50 per cent of the votes, the more secure its position is, not only because it comes nearer to obtaining the absolute majority by itself, but also because the second party is likely, by the same token, to be relatively smaller.

Thus the first condition is in itself both absolute and relative. The second condition is that the system should be a multi-party system: dominance is exercised most adequately (as can be seen in the economic world) if there is a multitude, and not simply a small number, of other firms. If, to take an extreme

position, the dominant party was faced with a large number of insignificant forces, each comprising 2 or 3 per cent of the votes, its dominance would be assured permanently. In practice permanent dominance may be obtained with a minimum of four solidly established parties, though dominance is not ensured, as can be seen from the example of Iceland in which the Independent party was out of office for three years. Even five parties are not fool-proof, since (but admittedly with great effort and after a split had taken place) the dominant Socialist party in Norway was thrown out of office by a coalition of all the others. But these are very exceptional occurrences. On balance, a dominant

party is fairly safe in a five-party system: for all five countries, the two cases of

Norway and Iceland were the only ones in which the dominant party was out of power.

There is, moreover, a third and subsidiary condition. Dominant parties thrive

particularly if they can count on the potential support of satellite parties on at

196 J. BLONDEL

Page 19: Blondel Party Systems

least one ideological side. The Norwegian and Icelandic dominant parties suf- fered from not being able to generate such satellites; the Swedish, Danish, and Italian dominant parties (to which must be added the French Gaullists-and indeed the German CDU during the short period when it moved from its

original "Dutch" position to its present situation) have on the other hand tended to benefit from the existence of satellite parties and, in the Italian case, to

generate them. When, as in Italy, the dominant party is relatively weak with

only the minimum electoral strength entitling it to be dominant, the condition of satellite creation and development becomes particularly critical. But the condi- tion exists in all cases of this type, as these "dominant" parties usually do not reach even a bare absolute majority of seats and remain somewhat below the line.

The representation of the political parties in the government, either succes-

sively or simultaneously, is therefore dependent upon the balance of the political parties. Unbalance creates or multiplies distortions. Yet, this type of unbalance can remain permanent in Western democracies. The distorted representation of Scandinavian countries, of Italy, and possibly of France has not created serious

political problems. Admittedly, in France and Italy, present changes in electoral

alignments or in the representation in the government seem to indicate that the

existing unbalance is felt as a problem which needs to be solved. But in the three Scandinavian countries, the right appears to have accepted its traditional fate: perhaps the recent victory of the bourgeois parties in Norway will help to maintain the status quo, for it suggests that the dominant party may be put, at least for a time, in opposition.

While distortions elsewhere are, on average, lower than they are in the coun- tries with a dominant party, recent changes in coalition patterns are leading to reduced distortions in the two countries in which they are highest, Finland and

Germany: the return of the Communist party to the Finnish government and the establishment of the grand coalition in West Germany are all conducive to a sizeable reduction of the distortion level. The previous conclusion about unbalance should therefore perhaps be restated: behavioural patterns may lead

automatically to a modification of the rules about governmental formation when the level of distortions is sizable-provided, however, that the structural condi- tions (dominant party) or the political attitudes (party government, as in Australia) do not limit the flexibility of the adjusting mechanisms.

Representation of the various political parties thus depends very markedly upon the nature of the party system as well as upon the ideology relating to

party government which prevails in the country. One-party government will ensure representation only if there is a fairly even balance, implying therefore a

two-party system and indeed a two-party system which does (automatically, by some divine hand) produce a change of government at a regular interval:

one-party government thus depends, like the traditional capitalist system, on the

goodwill of unknown underlying forces. Multi-party government, if left to its own devices as in Holland, Switzerland, and (though perhaps oddly) in the tradi- tional French regime, does ensure good to moderate representation-but the con- dition which is required is that a party should not be ostracized by the others (or make itself ostracized by its behaviour). The two-and-a-half-party system, if flexible about the rules of the game, is perhaps the system which ensures best (and most meaningful) representation. It oscillates between one-party government

Western Democracies 197

Page 20: Blondel Party Systems

and a grand coalition, and these oscillations give flexibility to the arrange- ments and make it possible to avoid permanent non- or under-representation of some groups. In fact, if looked at from the point of view of the left (which is weaker in two-and-a-half-party systems than in two-party systems), the two-and- a-half-party system has made party representation in government easier; it would have made for very good representation in Germany had not Adenauer attempted a systematic but unsuccessful move towards a two-party system. The distortion levels of systems with dominant parties are serious, though they appear to be, in the context of stable Scandinavia, tolerated by the electorate. The distortions of two-party systems are potentially serious, if the divine hand does not act to make the pendulum swing. Two-and-a-half-party systems have shown some capacity to operate flexibly and to generate some representation. Is it at the price of less stable, and therefore probably less efficient government?

DURATION OF GOVERNMENTS

We noted earlier that governments could be divided into four groups according to whether they lasted five years or more, three years or more, two years or slightly more, or about one year or even less. This duration is unquestionably influenced by the type of party system prevailing in the country. The longest duration can be found in two-party systems, even if the United States is excluded, the shortest among multi-party systems without a dominant party. The other two groups stand in the middle (see Table IX). There is no overlap between the first and fourth groups: Austria with the most short-lived govern- ments among the two-party systems had a slightly higher average than Holland, the country with the highest average among the multi-party system countries without dominant parties.

There is little difference, on the other hand, between countries which have a two-and-a-half-party system and countries with a multi-party system of the dominant-party variety: variations are considerable, from Canada to Belgium and from Sweden to Italy. In both groups (and indeed even in the two-party group if one compares Austria to the other countries), countries which are normally governed by a coalition are more likely to have unstable governments than countries which are governed by one party. This result is, of course, partly a function of the index used to measure ministerial crises: what is a reshuffle in Britain (e.g., sacking ministers as in 1962) becomes a ministerial crisis in

Page 21: Blondel Party Systems

Austria, though in the end (at least up to 1966) the same parties became partners again in the coalition. But, in psychological terms, coalition break-ups, even if followed by a rejoining, appear to be ministerial crises; they usually mean that the machinery of the state comes to a halt for a period, sometimes lasting several weeks; they involve the machinery of the state to resolve the conflict (in particular the action of the head of state or a formateur appointed by him). They do not take place in the privacy of the prime minister's mind or among a few colleagues. They are public events and, as such, contribute to mould attitudes about the political system and to have an effect on the efficiency of government.

Two factors thus appear to contribute to the relative duration of governments in parliamentary systems: the fact that the system is a straight clash between two parties and the fact that one party government prevails. The two factors are quite clearly connected: one-party governments are not possible without at least one large party, except on a temporary basis. But, as we noted, the ideology of one- party government is accepted in some countries, particularly in Anglo-Saxon countries, while the notion of coalition can prevail even where it is not strictly necessary, as in Austria or during at least one period of Adenauer's Germany. On balance, although the link between the two factors leads to some uncertainty, it does seem that one-party government, rather than the two-party system, is the factor contributing most decisively to the stability of government. None of the countries which have had party government during most of the period has a low record of governmental stability.

Conversely, no country in the coalition group had governments which lasted more than about three years. Germany is indeed the only coalition country which belongs to this group and its place there appears directly consequential upon the enterprise of Adenauer: events since 1963 show that post-Adenauer governments may not last for even as long as three years. While practically all the one-party governments are to be found in the top two categories (more than five years and about three years), these categories may soon no longer include any of the countries which are ruled by coalitions.

The duration of governments can therefore be said to be essentially dependent on the presence in power of a "team," and, almost certainly, on the presence of a team leader who does not merely arbitrate, or spend much time in arbitrat- ing, divergences between coalition partners. The existence of a two-party system, in the strict sense in which we defined it here, does apparently help in that a two-party system increases the probability that the ideology of one-party govern- ment will prevail in the political culture. It also constitutes a sufficient though not a necessary condition for the presence of a large party which can take alone- or at least is in a position to claim that it can take alone-all the posts in the government.

But where (and when) the two-and-a-half-party system, or even the multi- party system with a dominant party, is so configured to allow one party to take power alone at least fairly frequently, governmental stability is-or may be-equally assured. Coalition, whether small or large, appears directly antago- nistic to stable government, though differences can also be large, from Austria to France and from the Netherlands to Finland. The way to ensure both stability and coalition therefore seems to be the Swiss way. When, as in Switzerland but

Western Democracies 199

Page 22: Blondel Party Systems

nowhere else, the coalition system is institutionalized and when, as a result, the parties have little leeway to try different types of combinations ranging from grand to small coalitions and including various types of small coalitions, the governmental coalition can remain stable. Perhaps the Swiss model is inapplicable to large countries; indeed the alternate presence and absence of Socialists in the Swiss Federal Council shows that, even where coalition is institutionalized, some instability does take place. But the stability of government which one-party government can give could not, it seems, be achieved as long as the rules of the game remain uncertain in relation to coalitions, their size, and their type. Whether the efficiency of government is directly affected needs to be considered in the light of other indicators as well, such as, for instance, legislative analysis. But to the extent that the duration of government does affect, as it clearly appears to do, the efficiency of its work, the coalition system and the absence of one (but not necessarily more than one) large party appear instrumental in increas- ing inefficiency.

Stability and fair representation of parties in government are difficult to achieve jointly in Western systems of government. Clearly, if the divine hand is at work, the two-party system can provide, over time, successive representation and reasonable efficiency. But several examples indicate that the divine hand can be at rest. In fact, only one of the five countries which belong to the group, the United States, appears able to achieve a relatively high level of successive repre- sentation; and this conclusion can be drawn only provided little attention is paid to the relative weight of the subgroups which divide American parties in Congress: if these were to be taken into account, the over-representation of the right might appear as large in America as in Britain, if not perhaps as in Australia. Coalition government has provided means of achieving better repre- sentation of the various political forces in some Continental countries and, possibly as a result, obliged these forces to compromise on their policies. But this is clearly at the expense of possibilities of long-term action: deadlock in government and lengthy governmental crises are the price paid for such "true" representation.

Yet, as was noted earlier, the four types of party systems, with their relative efficiency and representativeness, have remained surprisingly stable. Even the system of the dominant party, though clearly unfair to those who do not move into the government, shows very little sign of being seriously challenged. Govern- mental patterns are clearly shaped. They provide solutions not only to the specific problems of the countries concerned (whether the presence of a large Communist party, or the ideology of one-party government, or the idea of equilibrium of political forces) but to the general problems of efficiency (and apparent efficiency) and representation (including apparent representation). No Western government appears to have solved both except by luck; and reflections on how to create or maintain the luck have been generally absent. Perhaps, however, behind the apparent lack of representation in government or the apparent lack of efficiency resulting from instability, other forces, through parliaments and the interest groups, succeed in promoting policies which counter- balance, to a large extent at least, some of the most apparent defects of the systems. Studies of governmental patterns should consider, through systematic studies of outputs, this efficiency and this representativeness.
