In a referendum held on 23 June 2016, the majority of the UK electorate voted to leave the European Union.

On 29 March 2017, in writing to European Council President Donald Tusk, the Prime Minister formally triggered Article 50 and began the two-year countdown to the UK formally leaving the EU (commonly known as ‘Brexit’).

This paper provides a timeline of the major events leading up to the referendum and subsequent dates of note, looking ahead to expected events as the UK and EU negotiate Britain’s exit.

The UK has long been expected to leave the European Union at 11pm on 29 March 2019. However, following a House of Commons vote on 14 March 2019, the Government is expected to seek permission to extend Article 50 and agree a later Brexit date.
