United Kingdom's planned withdrawal from the European Union

Brexit (/ˈbrɛksɪt, ˈbrɛɡzɪt/) is a movement that promotes that the United Kingdom (UK) leave the European Union (EU). The name "Brexit" is a portmanteau (merging two words together) of "British" and "exit".

On 23 June 2016, the UK made a referendum that asked whether the UK should leave the EU. The result was that 51.9% of the UK electorate (the main region of the UK) voted that the UK should leave the EU. The rest wanted the UK to stay in the EU. On 29 March 2017, the UK government said that they will definitely be leaving the EU. This started the procedure of Article 50 of the Treaty on European Union, a law that deals with countries that leave the EU. The UK was expected to fully leave the EU on 29 March 2019 at 11 p.m. UTC.[1] The deadline to leave was later changed to 31 October 2019.[2]

On 15 January 2019, Theresa May's government was defeated in the House of Commons by 230 votes in a vote on her deal to leave the European Union.[3]


Below is a timeline of major events relating to Brexit.[4]
