Candidates to succeed Liz Truss as the next Conservative Party leader only have until 2pm on Monday to line up their nominations.
The race is open now and will close on October 24, with candidates needing at least 100 nominations to go forward - five times as many as the last contest, when only 20 nominations were needed. As there are 357 Tory MPs, this means that only three will be able to go forward for election.
The process will be a lot quicker than the summer leadership contest, which Ms Truss won, which was held over three months and involved eight candidates.
