Brexit's Referendum

As promised in the election manifesto, Cameron set a date for a referendum on whether the UK should remain a member of the European Union, and announced that he would be campaigning for Britain to remain within a "reformed EU". The terms of the UK's membership of the EU were re-negotiated. The referendum came to be known as Brexit (a portmanteau of "British" and "exit") and was held on 23 June 2016. The result was approximately 52% in favour of leaving the European Union and 48% against, with a turnout of 72%.
