The European Union (Withdrawal) Act 2019, commonly referred to as the Cooper–Letwin Act, was an Act of the Parliament of the United Kingdom that made provisions for extensions to the period defined under Article 50 of the Treaty on European Union related to the United Kingdom's withdrawal from the European Union. It was introduced to the House of Commons by Labour MP Yvette Cooper and Conservative MP Sir Oliver Letwin on 3 April 2019, in an unusual process where the Government of the United Kingdom did not have control over Commons business that day. The Act was repealed on 23 January 2020 by the European Union (Withdrawal Agreement) Act 2020.
