Prime Minister Theresa May has today told a group of her colleagues that she will leave her post and make way for another party leader if her Brexit deal is passed through the House of Commons when it returns for a third 'Meaningful Vote' later this week.
According to those at the meeting, the PM said: "I am prepared to leave this job earlier than I intended in order to do what is right for our country and our party."
ITV Political Editor Robert Peston later took to Twitter to confirm that a source had said a Conservative leadership election would begin on May 22, 2019 if the PM's deal is passed.
The announcement to her fellow Conservative MPs came at a time when other Members of Parliament were debating a series of indicative votes, which the House will vote on. Anything that gains a majority in this way however is not legally binding for the sitting government. It's completely up to the PM whether or not she takes notice of them. Those votes will take place tonight.
Whether or not the PM can be trusted to be held to her promise today however, is anybody's guess. She has been a part of countless U-turns throughout her time in the post, and it wouldn't be out of her power to decide she actually will go ahead with trade negotiations, even if her deal does pass.
Usually, the Conservative Party would then be able to hold a vote of no confidence in the PM, but having already defeated one in December of last year, that wouldn't be an option for her MPs to chase until December of this year.
The Leader of the Opposition, Jeremy Corbyn, could however put forward a vote of no confidence in the government. If this was successful, a general election would be called and the Conservative Party's grip on power in the UK would be put at risk.
So, what happens next? Good luck if you'd like to make a guess...
