Candidates can start gathering in nominations from MPs now. To be successful a candidate has to have at least 100 MPs backing them. The maximum number of MPs in the field will be three and it could be less than that. There'll be a private hustings among MPs after the close of nominations. If there are three MPs on the ballot the MPs will then vote and whittle it down to two. Then there's going to be an indicative vote among the two if that's what we get down to. And then Tory party members themselves will have an online vote.
