The Leave and Remain campaigns defined British ‘Greatness’ in very different ways. The referendum reflects more than attitudes toward EU membership — it marks a new understanding of Britain’s role in the world, as our Postdoctoral Fellow Benjamin Martill argues in this piece. The end of the postwar consensus of liberal internationalism has important implications and needs to be taken seriously.
The ‘Great’ in Great Britain is a geographical term identifying the larger of the two British Isles (the other of which is, of course, Ireland). But this is not the way many Brits interpret the term. For greatness has also become a political category, referring not to British territory but to its venerable national attributes and its reputation on the international stage. What, we are often asked, makes Britain ‘great’?
Formerly this question might have been limited to the tabloid press and nostalgic television programmes. But in the age of rising populism across the globe and the election of Donald Trump as American president – on the promise of ‘Making America Great Again’ – the question has begun to take on more explicitly political qualities. Increasingly, individuals are asking what it means to be a ‘great’ power, what kind of actions ‘greatness’ requires, and how – or whether – to ‘Make Britain Great Again’. Nowhere was this emerging politics of ‘greatness’ more evident than in the referendum campaign over Britain’s EU membership in 2016.
For Brexit was about more than Britain’s relationship with Europe. The arguments (successfully) used by the leave campaign critiqued not just the EU but also the broader liberal consensus in British foreign policymaking on which British accession had, in part, been premised. Moreover, the position on which the leave campaign based its opposition to the EU was remarkably consistent in its views of Britain’s role in the world. The Britain they sought would be a great, global, free-trading nation, once freed of the shackles of EU membership. For “Britain needs fundamental change so that we can control our borders, trade freely around the world, and return power to Parliament to block harmful EU rules “. The UK put its own citizens first, instead of subsidising or otherwise trying to change other countries. As one Grassroots Out leaflet complained : “How about we take care of our own problems first, and leave [sic] EU”. And an independent Britain would cease to provoke conflict, especially with Russia, which the EU was accused of doing. UKIP, for instance, noted  that the EU “failed in Yugoslavia [and] provoked a war in Ukraine”. Above all, the leave campaign stressed  one important message: Brexit was about “putting the ‘Great’ back into Great Britain.” In short, post-Brexit, Britain would “re-join the rest of the world”. 
The remain campaign saw things very differently. This is not to say they didn’t believe in Britain as a ‘great’ power. Indeed, even the Labour remain campaign argued  that “Britain is more powerful in Europe… If we leave Europe, Britain will be weaker, not stronger” and exhorted their supporters to “Vote for Britain’s place as a world power”. The difference was that the leave campaign viewed the requirements of greatness very differently from how the remain camp did. They saw Britain’s greatness as a product of its commitment to a regulated and legalised international order and its membership of a dense network of overlapping institutions, of which the EU was but one example. “Britain is a member of more international organisations than any other country”, the European Movement noted  . “We sit at all the top tables; UN, NATO, EU, Commonwealth, G8, IMF, World Bank, etc., and we are able to use our unique network to influence the course of world events”. Remainers associated greatness with the promotion of British values – democracy, human rights, rule of law – rather than the demonstration of British power. Moreover, remain supporters regarded the EU as an enabler, not a constraint, in this regard, since British membership had an amplifying effect on the UK’s political, economic, and military clout. As Lyn Brown, a Labour MP remarked : “Britain is more prosperous, better protected and more powerful in the modern world because of our membership of the EU… Britain’s EU membership gives us a strong voice on the world stage”. Maintaining Britain’s EU membership, as a result, was about  “Keeping Britain Great”.
The prominence in the campaign of Britain’s role in the world matters because it signals the politicisation of a policy domain hitherto marked by consensus rather than conflict. Since 1945 the dominant discourse underpinning the conduct of the UK’s foreign relations has been that of liberal internationalism, in its various guises. One aspect of this could be found in the UK’s support for the establishment of a global free-trading regime and on institutions to regulate international order and ‘restrain’ anarchy. Another element was the British contribution to the collective security of ‘the West’ against its various authoritarian and illiberal enemies. Moreover, there was a key normative element, with British ‘greatness’ thought to reside in its promotion of liberal values across the globe, from human rights and democracy to economic liberalisation and the rule of law.
Liberal internationalism found support across diverse political constituencies, especially the Labour right, Conservative moderates, and the Liberals (and subsequently Liberal Democrats), such that a ‘postwar consensus’ was said to exist between the parties. Opposition to liberal internationalism did emerge from time to time, of course, and from within specific constituencies, most notably the traditionalist wing of the Conservative party. When it did, moreover, it followed a familiar pattern associated with support for old-school realpolitik, emphasising political independence, the balance of power, and a narrow definition of the national interest. And yet these views were never sufficient to unseat liberal internationalism as the dominant discourse animating Britain’s global role.
Fast-forward to 2016 and this political situation had changed considerably. The political centre-ground upon which the post-war consensus was based had collapsed. The Conservative party clung to power by aping the policies of its UKIP challengers on the right, heralding a return to a more virulent Eurosceptic position and putting more traditional members in the driving seat. Under Jeremy Corbyn, the Labour party moved away from the centrism of the Blair years. The Liberal Democrats, meanwhile, saw a precipitous drop in support after propping up David Cameron’s coalition government, widely blamed for the damaging post-recession austerity policies. These factors culminated in the rise of an alternative realist narrative of Britain’s role in the world and, ultimately, to the game-changing vote to leave the EU in the 23 June referendum. The victory of the Leave campaign lent further support to the narrative of a great, global Britain, especially once it became clear Theresa May interpreted the result as a mandate for a ‘hard Brexit’. In language reminiscent of UKIP priorities, May called in her Lancaster House speech  for a “great global trading nation”. The Conservatives’ appropriation of the UKIP position did not go unnoticed. Nigel Farage, for one, said  he could “hardly believe that the PM is now using the phrases and words that I’ve been mocked for using for years”.
The politicisation of British foreign policy is one of the lesser-studied aspects of the Brexit vote, but it deserves to be taken seriously, not least because it challenges the expectations of scholars and policymakers alike that British foreign policy after Brexit will see the continuation of liberal internationalism without the EU connection. Since opposition to the EU was based, in part, on opposition to liberal internationalism, this discourse has also fallen from favour in the post-Brexit fallout, at least as far as the presently ascendant Brexiters are concerned. This ideational shift needs to be taken seriously. Discourses are not just empty rhetoric. They give politicians and policymakers representations of the world which inform their identification of problems, priorities, and appropriate solutions. And they foreclose some policy options while opening up others. The politicisation of Britain’s foreign policy agenda – built upon institutionalisation, trading regimes, democratisation, foreign aid, and ‘Western’ deterrence – means these categories cannot be taken for granted in the years to come. We need to acknowledge this challenge to liberal internationalism if we are to fully understand future debates and changes in UK foreign policy, for Brexit is about much more than Britain’s EU membership.
