Our political editor Paul Francis has provided expert analysis on the upcoming vote of confidence in Prime Minister Theresa May:
"Theresa May's leadership was already hanging by a very narrow thread and it is now perilously close to breaking point.
By this evening she will know if she has to hand over the keys to Downing Street in what would be a dramatic turn of events.
Given her fortitude it seems at this stage she is unlikely to go without a fight.
The question is one of arithmetic- can she marshall enough support among MPs to continue.
As to possible successors it seems some of the likely suspects are keeping their counsel.
One thing the Conservative party is renowned for is being fairly ruthless when it comes to ditching leaders when they become an electoral liability- and there are growing numbers of MPs who may be calculating they have reached that point."
