Brexit negotiations
Between 2017 and 2019, representatives of the United Kingdom and the European Union negotiated the terms of Brexit, the UK's planned withdrawal from membership of the EU. These negotiations arose following the decision of the Parliament of the United Kingdom to invoke Article 50 of the Treaty on European Union, which in turn followed the UK's EU membership referendum on 23 June 2016 in which 52% of votes were in favour of leaving. The negotiating period began on 29 March 2017, when the United Kingdom served its withdrawal notice under Article 50.
