Peter Mair Political Opposition and the European Union1 ONE OF THE PRINCIPAL REASONS TO ADDRESS THE ISSUE OF POLITICAL opposition in the context of the European Union is that there seems to be a lot of it about. Indeed, when France and the Netherlands voted in early summer 2005 to reject the proposed new European constitution, they seemed to epitomize a growing mood of scepticism about Europe that could be sensed more or less throughout the enlarged Union. In the past, when approval of the European project has been explicitly demanded – in referendums in France, Ireland, Denmark and the UK, for example, as well as in the accession refer- endums in many of the newer member states – it has almost always been given. Where it has been denied, as in Denmark in 1992 and Ireland in 2001, the question has been asked again in a somewhat different form, and then eventually consent has been given. More often, of course, consent was never explicitly demanded, and hence it was always assumed to exist. In the absence of any serious outbreak of opposition, agreement was taken as given. This was the essence of the so-called permissive consensus: there was a consensus in the sense that there was agreement across the political mainstream that Euro- pean integration should be furthered, and it was permissive in the sense that the high levels of trust in the political elites during these years ensured that there was almost always popular deference to their commitments.2 1 This is a slightly revised version of the Government and Opposition/Leonard Scha- piro Annual Lecture, delivered at the Annual Conference of the Political Studies Association, Reading University, 5 April 2006.

When France and the Netherlands voted opposition to the proposed constitution, they did so with relatively large majorities on the basis of relatively large turnouts. Of the 62 per cent who voted in the Neth- erlands, fewer than 40 per cent voted Yes; of the 69 per cent who voted in France a few days earlier, only 45 per cent voted Yes. Less frequently recalled is the July 2005 referendum in Luxembourg – one of the two major centres of the European Union – when 90 per cent of the electorate voted, and when the majority in favour proved to be a surprisingly muted 57 per cent.3 If so many Luxembourgeois had doubts about the project that was effectively located in their midst, then support for Europe was certainly ebbing. Survey evidence tells much the same story. In a recent paper presented to a conference on Euroscepticism, Catherine Netjes and Kees van Kersbergen show that between 1991, when the Maastricht Treaty was being finalized, and 2003, popular support for the EU fell by some 17 per cent across the EU-15 as a whole. The fall was most pronounced in the Netherlands and France, but was also substantial in the UK, Germany, Belgium and Italy. Only in Luxembourg, where the doubts were evident in 2005, as well as in Ireland, Sweden and Austria, did the more recent Eurobarometer polls point to a slight growth in support,4 and even in Ireland the question regarding approval of the Nice Treaty had to be posed twice before an endorse- ment was forthcoming. Of course, there are a lot of extenuating circumstances at work here. Voters in both France and the Netherlands were clearly con- cerned about the enlargement of the EU, as well as the proposed further expansion to Turkey, and even though this was not formally an issue in the constitutional referendum, it clearly played a role in helping to determine voter attitudes. Scepticism about the euro and its effect on hidden price inflation may also have been important, even though this too was not part of the issues that were formally put explain why the public had voted as it had, . . .

There are governments in the EU, of course, and there is opposition to the EU, but there is little in the way of a linkage between these two that would make the government–opposition relationship relevant to EU practice. When Schapiro launched Government and Opposition in 1965, and when Dahl published his volume on political oppositions a year later, they were not breaking completely new ground. Almost 10 years earlier another major figure in European political science, Otto Kirchheimer, had published a now famous and widely quoted essay on what he referred to as ‘the waning’ of opposition in Western democracies, in which he identified three different modes in which opposition could be understood.9 The first of these was defined as ‘classical opposition’, and was drawn from the experience of the United Kingdom polity from the eighteenth century onwards, and reflected a system in which those not in government opposed and offered alternatives to the policies pursued by the government, while at the same time recognizing the right of that government to govern. Second, there was what he called the ‘opposition of principle’, in which those opposed to the government of the day objected not only to the government and its policies, but also to the whole system of governance. In other words, they opposed the government and also denied it legitimacy. Finally, there was what he called ‘the elimina- tion’ of opposition, something that occurred when the polity expe- rienced government by cartel, and when no substantive or meaningful differences divided the actors that were ostensibly com- peting against one another. If we relate this distinction to the categories that were later devel- oped by Dahl in his Political Oppositions volume, then we can think of classical opposition as being that which is directed at the policies of the government; opposition of principle is that which is directed at the polity; and the elimination of opposition is that which occurs when opposition is directed only against the personnel of government. 9 Otto Kircheimer, ‘The Waning of Opposition in Parliamentary Regimes’, Social Research, 24: 1 (1957), pp. 127–56. For a valuable recent overview of Kirchheimer’s analyses of the post-war democracies, see André Krouwel, ‘Otto Kirchheimer and the Catch-All Party’, West European Politics, 26: 2 (2003), pp. 23–40. 5POLITICAL OPPOSITION AND THE EUROPEAN UNION © The Author 2007.

IP address: 88.1.61.219, on 05 May 2017 at 23:18:16, subject to the The key point to understand here, however, is that these are not just discrete modes of opposition, but are actually related to one another. For Kirchheimer, for example, there had been a more or less unstoppable trend among the post-war democracies away from classical opposition, and away from an opposition of principle, towards a situation in which opposition was effectively eliminated – hence ‘the waning of opposition’. This trend was also noted by Dahl, who pointed to the growing extent of agree- ment among political actors and to the decline in opposition, and who referred quite elegantly to the emergence of a ‘surplus of consensus’.10 Over and above any general trends that might be noted with regard to these different modes of opposition, though, there was also another relationship between them that was emphasized by both Dahl and Kirchheimer, as well as by Schapiro, and which is very relevant in this context. It is perhaps an obvious point, but it is still worth recalling and underlining: anti-system opposition, or opposi- tion of principle, is undermined when more scope is afforded to classical opposition. Conversely, when classical opposition is limited or constrained, it then becomes more likely that critics will mobilize around an opposition of principle. In other words, if political actors lack the opportunity to develop classical opposition, then they either submit entirely, leading to the elimination of opposition, or they revolt. We need look no further than the sad history of Northern Ireland in the 1950s and 1960s and beyond to see the truth of this statement.11 Or, as Schapiro put it in his editorial in the first issue of Government and Opposition, ‘revolutions become necessary because the polity has failed to integrate opposition within government, and to provide it with an outlet’.12 According to Dahl, back in 1966, the long-term path of develop- ment of democratic institutions has been marked by three major milestones. The first of these established the right of citizens to participate in governmental institutions by casting a vote. The 10 Dahl, ‘Reflections on Opposition’, p. 19. 11 See, for example, Richard Rose, Governing without Consensus: An Irish Perspective, London, Faber and Faber, 1971; and Ian McAllister, The Northern Ireland Social Demo- cratic and Labour Party, London, Macmillan, 1977. 12 Shapiro, ‘Foreword’, p. 3. 6 GOVERNMENT AND OPPOSITION © The Author 2007.

The third established the right of an organized opposition to appeal for votes against the government and in elections.13 But while the first two of these milestones have also been established in the case of the EU institutions, the third has not. That is, while we now enjoy the right to participate in EU decisions by casting a vote, whether for our putative national representatives who go to the various Councils, or for our European representatives who go to the European Parliament in Strasbourg; and while we also enjoy the right to be represented in Europe – by all accounts, and despite its manifest shortcomings, the European Parliament is a representative body;14 we emphatically lack the right to organize opposition within the system. We lack the capacity to do so, and, above all, we lack an arena in which to do it. Once we cannot organize opposition in the EU, we are then almost forced to organize opposition to the EU. To be critical of the policies promulgated by Brussels is therefore to be critical of the polity; to object to the process is therefore to object to the product. Following Kirchheimer, in other words, we either submit, and hence we accept the elimination of opposition, or we mobilize an opposition of prin- ciple and become intrinsically Eurosceptic. DEPOLITICIZATION15 Why should this be the case? The obvious answer is that we cannot organize opposition in the EU – we cannot appeal for votes against a government in elections or in parliament – because the EU itself has been depoliticized. Opposition demands political debate, and, as 13 Robert A. Dahl, ‘Preface’, in Dahl, Political Oppositions in Western Democracies, p. xiii. 14 See, for example, Herman Schmitt and Jacques Thomassen (eds), Political Rep- resentation and Legitimacy in the European Union, Oxford, Oxford University Press, 1999. 15 The following section draws closely on part of my online paper ‘Popular Democ- racy and the European Union Polity’, European Governance Papers (EUROGOV), C-05-03 (2005), at http://www.connex-network.org/eurogov/pdf/egp-connex-C-05-03.pdf; for related arguments, see Peter Mair, ‘The Europeanization Dimension’, Journal of European Public Policy, 11: 2 (2004), pp. 337–48; and Peter Mair, ‘The Limited Impact of Europe on National Party Systems’, West European Politics, 23: 4 (2000), pp. 27–51. 7POLITICAL OPPOSITION AND THE EUROPEAN UNION © The Author 2007.

[often reflecting] differences in conceptions of nationhood, over domestic priorities and over external strategies’, and these, when translated to the European level, would be equiva- lent to the current divisions about the desired shape, depth and territorial extension of the European integration process.19 In their original schema, Lipset and Rokkan also specified a second or functional axis that cut across the territorial dimension. At one end of this dimension were grouped various interest-specific conflicts over the allocation of resources, conflicts that were seen as pragmatic in nature and as capable of being solved ‘through rational bargaining and the establishment of universalistic rules of allocation’. At the other end were grouped the more ideological oppositions, in which the conflict was not about particular gains or losses but instead concerned ‘conceptions of moral right and . . . the interpretation of history and human destiny’.20 This second dimension is also perfectly compatible with the translation of this scheme onto the European level. In this case, as in the case of the Lipset–Rokkan nation-building model, the second axis is not about Europe or Europeanization as such, whether specified in terms of institutionalization or penetra- tion, but rather takes Europe as a given and divides instead along strictly functional conflicts, sometimes interest-specific and some- times ideological. Conflicts that occur along this dimension take no position on the question of Europe as a polity, but are more con- cerned with the allocation of resources within whatever version of Europe happens to exist at the time. In sum, there are two dimensions of competition involved here, the Europeanization dimension and the functional dimension. The one concerns the shape and reach of the increasingly institutional- ized European Union political system, while the other concerns policy areas in which there is already an established EU competence, but in which there are disagreements about approach and about priorities. In addition, and as outlined above, there are also two channels of representation within the EU system; that is, there are 19 Lipset and Rokkan, ‘Cleavage’, p. 10. For a recent wide-ranging application of Rokkan’s framework to the process of European integration, see Stefano Bartolini, Restructuring Europe, Oxford, Oxford University Press, 2005. 20 Lipset and Rokkan, ‘Cleavage’, p. 11. 10 GOVERNMENT AND OPPOSITION © The Author 2007.

IP address: 88.1.61.219, on 05 May 2017 at 23:18:16, subject to the two channels through which citizens can hope to exert influence on, or control over the outputs of the system. The one channel works through European elections and the European Parliament, an insti- tution that has an increasingly important voice and authority in the policy-making process, and hence on the outputs of the EU, but which has no real say over the constitutional structures or even over the appointment of the political executive. The other works through national elections and national parliaments and governments, that is, within the arena that has the exclusive authority over constitutional questions. In principle, then, it should be possible to match these dimensions and channels to one another, and, at least at first sight, it should also be obvious how they fit together. As far as opposition on the Europeanization dimension is concerned, for example, and most especially as far as opposition to the institutionalization of Europe is concerned, the competences of the various institutions are such that one would expect this to be channelled through the national route. It is here, and only here, that the relevant authority lies. As far as opposition on the functional dimension is concerned, on the other hand, while this might also be channelled through the national route, since some of the relevant authority is also located here, the expectation is that this should mainly be focused on the European channel, and through the European Parliament, since it is along this dimension that the main competences of the Parliament seem to lie. To be effective, therefore, it would seem that representation via the national channel is best invoked for opposition along the European- ization dimension, whereas representation via the European channel is best invoked for opposition along the functional dimension. In practice, however, the real-world patterns of contestation tell quite a different story. That is, when we look at the debates and programmes that are found in each of the channels, we tend to find opposition regarding the institutionalization of Europe being voiced within the European channel, where no relevant competence lies; whereas opposition along the functional dimension is usually invoked in the national channel, even though on this dimension authority is shared with the European channel. The result is then simple to see. The choices in both channels become increasingly irrelevant to the outputs of the system, and the behaviour and preferences of citizens constitute virtually no formal constraint on, or mandate for, the relevant policy makers.

Oppo- sition, even when it exists, is almost by definition ineffective, and hence it becomes either muted and submissive – in Kirchheimer’s sense, it is eliminated – or it is transformed into an opposition of principle. Because we cannot mobilize opposition in Europe, and because we are denied an appropriate political arena in which to hold European governance accountable, we are almost pushed into organizing opposition to Europe. THE SEDATED GIANT How can we account for this evident evasion of opposition in Europe? How do we explain the failure to mark Dahl’s third major milestone in the development of democratic institutions at the EU level? In the short run, the answer, at least in principle, is very simple, and especially so when viewed from a supply-side theory of political competition: the system is driven by the choices made by party and political leaders when they contest elections and by the strategies that they adopt in both channels of representation. That is, and again with few exceptions, political leaders dealing with Europe choose to contest elections on issues in which those elections cannot prove decisive, and to exclude those issues on which the elections can prove decisive. They prefer to talk about the institutionalization of Europe when competing in elections to the European Parliament, where it is largely irrelevant, and they prefer not to raise these questions when competing in national elections, where it matters.21 The result is the remarkable depoliticization of the Europeaniza- tion dimension. There may well be a potential for conflict over Europe – over its reach, its form, and its sheer size – but, at least as yet, the parties that contest elections, particularly at national level, seem to want to push this to the shadows. The preference appears to be that Europe not be contested – at least within the mainstream. To 21 Although this is generally true for the mainstream parties in particular, the most extreme example of such displacement comes from the fringe, the Danish June Movement and People’s Movement. Again the EU chooses to fight its anti-European battle in the electoral arena of the European Parliament rather than in that of the Folketing. The two parties win a lot of support – almost 25 per cent in the 1999 round of European Parliament elections – but they are also clearly choosing, deliberately so, to fight in the wrong arena. 12 GOVERNMENT AND OPPOSITION © The Author 2007.

IP address: 88.1.61.219, on 05 May 2017 at 23:18:16, subject to the making process at the domestic level, it fails to compensate for this reduction by any commensurate repoliticization at the European level. What is being lost on the swings is not being gained on the roundabouts. Political conflict in this sense becomes undermined in Europe, and by Europe. EUROSCEPTICISM AND POLITY-SCEPTICISM Let me come to a conclusion and see where this might have taken us. In the first place, and following Dahl’s categories, it is clear that the EU misses the third great milestone that has marked the path to democratic institutions in the nation-states. That is, we are afforded a right to participate at the European level, even if we may now choose to avail ourselves of that right less frequently; and we are afforded the right to be represented in Europe, even if it is sometimes difficult to work out when and how this representative link functions; but we are not afforded the right to organize opposition within the European polity. There is no government–opposition nexus at this level. Second, and again following Dahl, as well as Kirchheimer and Scha- piro, we know that a failure to allow for opposition within the polity is likely to lead either (a) to the elimination of opposition, and to more or less total submission; or (b) to the mobilization of an oppo- sition of principle against the polity – to anti-European opposition and to Euroscepticism. Third, this development is also beginning to reach down into the domestic sphere, in that the growing weight of the EU, and its indirect impact on national politics, also helps to foster domestic democratic deficits, and hence also limits the scope for classical opposition at the national level. Here too, then, we might expect to see either the elimination of opposition or the mobilization of a new – perhaps populist – opposition of principle. Part of the problem here is that it is increasingly difficult to sepa- rate out what is European and what is national. In other words, as European integration proceeds, it becomes more and more difficult to conceive of the member states as being on one side of some putative divide, with a distinct supranational Union sitting on the other. Instead, we usually see both together and at the same time. Thus, for example, we have one approach in the literature on the EU that emphasizes how Europe ‘hits home’, while we have another and more recent approach that emphasizes how home – or the 15POLITICAL OPPOSITION AND THE EUROPEAN UNION © The Author 2007.

IP address: 88.1.61.219, on 05 May 2017 at 23:18:16, subject to the nation-state – ‘hits Europe’.23 In reality, each ‘hits’ and hence inter- mingles with the other, so that we might well conceive of what the great Irish writer Flann O’Brien might have called ‘a molecular theory of Europe’.24 The EU is also the member states. If, though, in practice, it becomes difficult to separate out what is European and what is domestic; and if, in practice, the two become ever more closely bound up with one another, it then follows that dissatisfaction with Europe must also entail a more generalized ‘polity-scepticism’. In other words, when we talk about Euroscepti- cism, and about opposition to Europe, we are also sometimes talking about scepticism and opposition towards our own national institu- tions and modes of governance. This is a scepticism about how we are governed, and it is, in my view, a scepticism that is at least partially fostered by the increasingly limited scope for opposition within the system – whether that system be European or national, or both at the same time. This is also one of the reasons why our polities have now become such strong breeding grounds for populism. To a degree, this was foreseen by Dahl in his contribution to the first issue of Government and Opposition, when he talked about the decline of opposition and the ‘surplus of consensus’, and when he talked about the type of opposition that might develop in the Western democracies of the future. Speculating about that future, he pointed towards the possi- bility of the emergence an opposition of principle, and of an oppo- sition that would be directed at the mode of governing itself.

In brief, cyclists who ride their bikes often enough, especially on bumpy Irish roads, will transfer some of their molecules into the bike, while the bike will transfer some of its molecules into the cyclist. Eventually, the mix becomes so advanced that it becomes impossible to know which is the bike and which is the rider. On market days you might see old farmers who cycle a lot balancing themselves with one foot on the curb, or leaning with their shoulders against a gable wall, while late on cold evenings you might see their bikes edging closer to the fire. 16 GOVERNMENT AND OPPOSITION © The Author 2007.

By the democratic Leviathan I mean the kind of political system which is a product of long evolution and hard struggle, welfare-oriented, central- ized, bureaucratic, tamed and controlled by competition among highly orga- nized elites, and, in the perspective of the ordinary citizen, somewhat remote, distant and impersonal . . . . The politics of this new democratic Leviathan are above all the politics of compromise, adjustment, negotiation, bargain- ing; a politics carried on among professional and quasi-professional leaders who constitute only a small part of the total citizen body; a politics that reflects a commitment to the virtues of pragmatism, moderation and incre- mental change; a politics that is un-ideological and even anti-ideological. . . . This new Leviathan [is seen by many citizens] as too remote and bureau- cratized, too addicted to bargaining and compromise, [and] too much an instrument of political elites and technicians . . .25 Political opposition gives voice. By losing opposition, we lose voice, and by losing voice we lose control of our own political systems. It is not at all clear how that control might be regained, either in Europe or at home, or how we might eventually restore meaning to Dahl’s third great milestone on the road to building democratic institutions. 25 Dahl, ‘Reflections on Opposition’, pp. 21–2. 17POLITICAL OPPOSITION AND THE EUROPEAN UNION © The Author 2007.
