Brexit deal: How the numbers stack up against May

The Prime Minister is facing a challenging two weeks as she tries to persuade enough members of parliament to back her deal and get it through the Commons.
The 2017 election called by Theresa May saw her lose her majority meaning she has to rely on members of the Democratic Unionist Party to get anything through comfortably.
But Arlene Foster's Northern Irish block has already said it won't be supporting the deal Mrs May brought back from Brussels, so she will have to look elsewhere.
