Brexit, the United Kingdom's withdrawal from the European Union, officially took place on January 31, 2020, at 23:00 GMT. The process began with a referendum held on June 23, 2016, in which about 52% of British voters opted to leave the EU. After extensive negotiations and political developments over the following years, the UK formally left the EU on January 31, 2020, entering an 11-month transition period that ended on December 31, 2020.
