Theresa May’s plan A for Brexit was heavily defeated two weeks ago in the Commons. There are now six competing Brexit plans which MPs will have to choose from in the coming weeks: the Prime Minister's, Labour's, Yvette Cooper's, Dominic Grieve's and a compromise plan C from no-deal Brexiteers and moderate Remainer Tories. Below is a breakdown of each: what it is, who supports it and if it could work.

Theresa May’s official plan B

What is it?

The Prime Minister is seeking to revive her deal with Brussels after it was overwhelmingly rejected by MPs last week in an historic defeat. Mrs May has declined to say exactly what she intends to do, but aides believe that an amendment offering a "sunset clause" on the backstop – a hard date by which it must end – could help win over support for her deal. She is expected to tell the Commons before the votes on Tuesday that she wants to reopen the Withdrawal Agreement.

Who supports it?

The Government believes an amendment to the existing Brexit deal could help win over the DUP’s 10 MPs as well as a significant tranche of Tory Eurosceptics. Several Tories who failed to back her deal last week have said publicly that an assurance around the backstop would be sufficient to win them over. However, the Prime Minister remains under intense pressure to make sure any changes to the backstop are included in the Withdrawal Agreement itself – something the EU has ruled out.
