Since the Maastricht Treaty (1993), subsidiarity has guided the political process surrounding the distribution of competences between administrative layers in the European Union (EU). The EU’s subsidiarity regime affects the politics and governance of the EU, because the notion of subsidiarity allows for continuous negotiation over its practical use. The constant battle over subsidiarity implies that the notion changes its meaning over time and alters the power relations between different actors within the EU. Since the Lisbon Treaty (2009), subsidiarity has mainly strengthened the position of member states at the expense of the Commission.

Since the end of World War II a key question that successive U.K. governments have faced is what position the country should occupy in global affairs. Such a question stemmed from the legacy of Empire, which both offered global connections and at the same time financial demands in terms of the need to maintain a global footing. These issues came to a head when the United Kingdom applied (unsuccessfully) to join the European Community (the forerunner of the European Union (EU)) in the 1960s when the country was reappraising its position in the world. And while the United Kingdom eventually joined the Community in 1973, there remained an underlying skepticism about membership within the public at large as well as within sections of the Conservative and Labour parties. This suspicion gained more traction from the 1990s onward as the then EU appeared to be moving to a deeper level of integration in the wake of the Maastricht Treaty. This spurred on Euroskeptics in the United Kingdom to campaign for independence. To put a lid on this pressure for reform, David Cameron held a referendum on U.K. membership in 2016. His gamble that this would once and for all seal the United Kingdom within the EU by closing down the issue of withdrawal did not actually materialize, as the electorate voted to leave, which in turn set the country on a path to depart the EU in 2020. Yet, despite these developments, just as was the case in 1945, the United Kingdom is in many ways still searching for a role in the world in 2020.
