Labour leader Jeremy Corbyn called for a vote of no confidence in the government, following Theresa May’s Brexit deal being voted down.
The ‘noes’ vastly outnumbered those in support of the deal, at 432 to 202 - the biggest margin in recorded history.
After Mrs May responded to the result, saying that the government would make time for a no confidence vote should the opposition decide to hold one, Mr Corbyn confirmed that he would.
“We have no confidence in this government which is why I’m submitting a vote of no confidence in this government, and I’m happy to say it will be tabled tomorrow,” he said.
'People deserve clarity'
Speaking after the result was announced, Mrs May said she would meet with colleagues to determine how the deal could be amended into something the house would support.
“It is clear the house does not support this deal, but tonight’s vote tells us nothing about what it does support,” she said.

“Nothing about how, or even if, it intends to honour the decision the British people took in a referendum parliament decided to hold.
“People, particularly EU citizens who’ve made their home here, and EU citizens living in the EU, deserve clarity.
“First, we need to confirm whether this government still has the confidence of the house. I can therefore confirm that if the official opposition table a confidence motion this evening, in the form required by the Fixed Term Parliament Act, the government will make time to debate that motion tomorrow.
“If, as happened before Christmas, the opposition decline to do so, the government will consider making time tomorrow to debate any motion from the other opposition should they put one forward.”
'Secure backing of the house'

“If the house confirms its confidence in this government, I will then hold meetings with my colleagues, our confidence and supply partners the DUP, and senior parliamentarians from across the house, to identify what would be required to secure the backing of the house.
“The government will approach these meetings with a constructive spirit but given the urgent need to make progress we must focus on ideas that are genuinely negotiable.”
But Mr Corbyn said: "She’s only attempting to reach out now to keep her failed deal alive".
The no confidence motion will be held on Wednesday, January 16.
The DUP have previously indicated they would support the Tories in such a vote, and reports suggest they may do so on Wednesday.
