UK Labour leader Jeremy Corbyn has called a no confidence vote in Theresa May over Brexit after her deal was voted down in Parliament.
But when will it take place and what does this mean for the Prime Minister, and for Brexit?
When and why will the vote of confidence take place?
Minutes after the PM stood up to make a statement on the disastrous defeat of her Brexit deal, Jeremy Corbyn announced he would bring a no-confidence vote in Mrs May before the Commons.
Theresa May could be gone as Prime Minister within 24 hours after the move by Labour.
The vote of no confidence in the Government comes the wake of the PM's defeat by 432 to 202.
After the Labour leader formally tabled the motion, it was confirmed MPs will vote on whether or not to kick the Government out of power at 7pm TONIGHT (January 16) .
If the motion passed and MPs had no confidence, then they would have 14 days to pass one again and get that confidence back. The opposition could also do the same.
If they can't do it, then a general election would take place, just weeks before the Brexit date of March 29, 2019.
What will happen next?
But it appears unlikely a no confidence vote will go though, because Labour still doesn't have the backing of the Northern Irish party, the DUP.
The last time there was a formal no confidence motion tabled in Commons was 1993 - John Major called it in himself, and won by 40 votes.
And the last time a PM lost a no-confidence motion was in 1979 when Jim Callaghan lost by one vote, triggering the General Election that brought Maggie Thatcher to power.
Mr Corbyn is understood to believe he would lose any attempt at a full no confidence vote, because the DUP and rebel Tories would stand behind the Government.
Instead he hopes to peel off enough Brexiteers who want to see the PM gone but don't want an election.
Some MPs insisted Mrs May would be under huge moral pressure to resign if she lost the confidence vote.

She is safe from a vote of no confidence from her own party for another 12 months, after the ballot against her failed late last year.
With only six weeks to go until the Brexit deadline, an election could well lead to further delays with the UK's withdrawal from Europe - and increase the likelihood of a no deal exit.
