[1] Section 1 of the Act required the Government to allow Parliament to debate a motion to require the prime minister to seek an extension to the period in which the United Kingdom is to negotiate the terms of its withdrawal from the European Union ("Brexit") under Article 50(3) of the Treaty on European Union.

As such, Sir Oliver Letwin tabled a motion which would allow MPs to undertake proceedings on the second, committee, and third reading of the Bill in one day.

[4] The second reading passed by 5 votes,[5][6] after closing remarks given by Steve Barclay, Secretary of State for Exiting the European Union, making clear the Government's opposition to the Bill.

[31] With the Committee and Report Stages completed, the Bill moved to Third Reading, when it was passed without a vote and returned to the House of Commons.

[38][39][40] On 9 April 2019, the House of Commons debated a motion under the terms of the Act put forward by the Prime Minister, requesting approval for the UK to seek an extension to the Article 50 process to 30 June 2019.
