Brexit

In a referendum on 23 June 2016, 51.9% of the participating UK electorate voted to leave the EU. On 29 March 2017, the British government invoked Article 50 of the Treaty on the European Union; although revoking this might be legally possible, the UK is thus on course to leave the EU by March 2019.
