Theresa May has put a new motion before MPs that effectively asks parliament to allow her to continue negotiating to seek changes to the Irish backstop. MPs are permitted to amend the motion, which will be voted on on Thursday.

This is the second time May has submitted an amendable parliamentary motion after the defeat of her Brexit deal. In January, MPs successfully amended the motion twice.

The first amendment, supported by the government, was spearheaded by the Conservative MP Graham Brady and called for the government to seek “alternative arrangements” to replace the backstop.

The second came from Caroline Spelman and was a defeat for the government backed by rebel Tory MPs. It said the House of Commons rejected the possibility of a no-deal Brexit.

But several high-profile amendments were lost, including one by Yvette Cooper and Nick Boles that would have paved the way for legislation to extend article 50. Both Cooper and Boles have said they do not intend to bring their amendment back until 27 February, when May has promised the next update will be tabled.

Here is a look at the prime minister’s main motion and the amendments that have been selected by the Speaker.

May’s motion – DEFEATED

Theresa May’s motion was defeated after ERG Tories refused to support her approach to leaving the EU.

May’s defeat, by 303 votes to 258, showed the prime minister once again losing control of her own party in the crucial final weeks before Brexit.

May’s motion had said negotiations to come to a compromise on the backstop are continuing and “reiterates its support for the approach to leaving the EU expressed by this house on 29 January 2019”.

MPs were voting to accept both the Brady and Spelman amendments – and members of the pro-Brexit European Research Group did not want to vote to accept the latter. It would effectively have meant they had accepted parliament was against leaving with no deal, when many of their faction believe it is a viable option.

Labour’s amendment to force another vote – DEFEATED

The Labour frontbench, including Jeremy Corbyn and Keir Starmer, tabled an amendment that would force the prime minister to bring her deal back to the Commons or table another amendable motion by 27 February, just over a month before the UK is due to leave the EU. It was defeated 322 to 306.

The SNP’s amendment to extend article 50 – DEFEATED

The amendment by the Scottish National party calls on the government to extend article 50 by at least three months. The amendment was defeated 315 to 93.

An amendment to force the release of no-deal cabinet briefings – WITHDRAWN

Anna Soubry has withdrawn the amendment she tabled with Labour’s Chuka Umunna, both leading remainers. It demanded the government publish “the most recent official briefing document”, which has been given to cabinet ministers on the implications of a no-deal Brexit on business and trade. Soubry pulled the amendment after the government said on Thursday that it would publish the information she wants.
