Following its withdrawal from the European Union on 31 January 2020, the United Kingdom began negotiations on several free trade agreements to remove or reduce tariff and non-tariff barriers to trade, both to establish new agreements and to replace previous EU trade agreements. Withdrawal ended 47 years of membership during which all its trading agreements were negotiated by the European Commission on behalf of the bloc as a whole. The UK did not actually withdraw from the European Single Market and the European Union Customs Union (and its trade agreements) until 31 December 2020.
