Five other senior figures in May's Conservative Party have put their names forward to replace Theresa May.

Raab vowed to fight for a fairer deal on Brexit. Raab wrote in an article for the Mail on Sunday newspaper that to deliver Brexit successfully will require focus, discipline and resolve adding that as a former Foreign Office lawyer and Brexit Secretary, he has the experience.

Leadsom, who resigned from her former post as head of the Commons this week saying she no longer believed the government's approach would deliver Brexit, told the Sunday Times that if elected, the UK would quit the EU in October with or without a deal.
