Brexit Referendum (2016)

Action: Voted in a national referendum to withdraw from the European Union

Neutral: On 23 June 2016, the United Kingdom held a referendum on membership in the European Union. A majority of voters (51.9%) chose to leave the EU. The result initiated formal withdrawal negotiations under Article 50 of the Treaty on European Union, culminating in the UK’s exit from the EU on 31 January 2020.
