Letter sent from the UK to the EU

Following the debate and vote in the House of Commons on 19 October, it was necessary for the Prime Minister to send a letter, dictated by Parliament in the recent “Surrender Act” (European Union (Withdrawal) (No.2) Act 2019) fast-tracked through Parliament, to the EU requesting an extension, under Article 50, until 31 January 2020. There was no additional information enclosed, or required, detailing what the extension was actually for.

A letter was sent, as required on 19 October 2019, to the EU Council with a cover letter from Sir Tim Barrow, United Kingdom Permanent Representative to the European Union
