Withdrawal of the United Kingdom from the European Union The Terms of Withdrawal from EU (Referendum) Bills were a series of private member's bills of the Parliament of the United Kingdom to make provision for the holding of a second referendum in the United Kingdom and Gibraltar on whether or not to leave the European Union either before Article 50 of the Lisbon Treaty can be triggered or following the conclusion of negotiations by the Welsh Labour MP Geraint Davies.

[2] On 23 June 2016 the United Kingdom and Gibraltar voted by 51.9% to 48.1% to Leave the European Union in the 2016 EU membership referendum.

The original 2016-17 bill sought to hold the proposed referendum before Article 50 could be formally triggered by HM Government however the bill failed to pass before the United Kingdom triggered Article 50 on 29 March 2017 and the snap general election which was held on 8 June 2017.

This led to a second version of the bill which proposes to hold the referendum following the conclusion of negotiations between the Government and the European Union.

The bills give the proposed question to appear on ballot papers: Do you support the Government’s proposed United Kingdom and Gibraltar exit package for negotiating withdrawal from the European Union or Should the United Kingdom remain a member of the European Union?
