On 23 June 2016, the UK made a referendum that asked whether the UK should leave the EU. 51.9% of the UK electorate (the main region of the UK) voted that the UK should leave the EU, while the rest wanted the UK to stay in the EU. On 29 March 2017, the UK government declared that they will definitely be leaving the EU. The UK government had set up Article 50 of the Treaty on European Union, a law that deals with countries that leave the EU. The UK is expected to fully leave the EU on 29 March 2019 at 11 p.m. UTC.
