Theresa May is facing a vote of no confidence in her leadership of the Conservative Party tonight.
First, a brief reiteration of the rules as they stand: to survive, Theresa May simply needs a bare majority of Conservative MPs to vote confidence in her – that’s 158 MPs. There are no other candidates at this stage: it’s just a ballot paper asking Conservative MPs if they have confidence in her. If she loses, it triggers a full-blown contest in which she cannot be a candidate. If she wins, she is immune to further challenges for a year – so if May survives tonight’s vote, she is safe in post until 12 December 2019.
