"As Europe struggled to recover from recession, in 2015 the British prime minister David Cameron tossed Brussels a grenade. He said he would hold a referendum on the UK’s continued EU membership the following year. The torch of British Euroscepticism had passed from left to right. It was now Conservatives rather than Labour who were most anti-European. Cameron’s attempts to appease his ‘leave’ voters by negotiating reforms to the EU were dismissed by the ever cautious Merkel and, in June 2016, to Cameron’s surprise and dismay, the British electorate voted narrowly to leave the EU. The vote was taken as binding by the government. The date decided by Parliament for departure was March 2019."
