Theresa May has urged MPs to back her plans or face the prospect of "no Brexit at all" before heading to Brussels for talks with Jean-Claude Juncker, president of the European Commission.
Tory MPs lined up to demand the prime minister renegotiate parts of her Brexit deal during a fiery prime minister's questions session, where Ms May sought to sell the plan to her divided party.
Earlier, senior Tories including Amber Rudd and Damian Collins opened the door to a new referendum, as the prime ministers hopes of securing a parliamentary majority appeared to fade.
It also comes amid suggestions from Brussels that a summit to sign off on the draft withdrawal agreement on Sunday could be called off unless progress is made on finalising a political declaration on future relations.

Theresa May heads to Brussels on Wednesday to meet Jean-Claude Juncker in a bid to hammer out the final details of the Brexit deal with the EU.
The prime minister’s visit comes days ahead of a European summit to sign off the agreement, but amid a heated row in her own party over whether it should be backed.

Amber Rudd has admitted “anything could happen” if Theresa May’s Brexit deal is defeated and suggested MPs will then prefer a Final Say referendum to crashing out of the EU.
The new work and pensions secretary undermined the prime minister’s threat of “my deal or no deal”, saying: “There isn’t a majority in the House of Commons to allow that to take place.

Karen Bradley tells the Northern Ireland Committee that the controversial backstop plan could be resolved by alternative means, eg technological checks on the border.
The Northern Ireland Secretary is getting a bit of a hard time from the DUP during the session.
Jim Shannon, the MP for Strangford, said: "We are quite annoyed," by the PM's Brexit plans. He says he is a "team player" and has walked through the voting lobbies to support the government - as part of the confidence and supply agreement Theresa May has with the DUP.
However the backstop is a "red line" for his party.
Mr Shannon asks: "Why are you pursuing a policy that is at odds with the majority of MPs and why there's a need to pursue something that's so much against the confidence and supply agreement with my party?"
Ms Bradley says a hard border was unacceptable as it would break up the integrity of the UK.
She said: "The safeguards put in place, the reassurances given, the way that the EU dislike the backstop means as a legal construct, not as a person or country, there is no way that there will be a situation where we can be bound into the backstop indefinitely.
"The right thing to do is to accept the deal and to get the future relationship and make sure we never go into the backstop in any way."
She says the right thing to do is to accept the withdrawal agreement and make sure the UK never goes into the backstop. There would never have been an agreement without one, she says.
Mr Shannon says this is an insurance policy that you can't claim on and he fundamentally disagrees with her.
Jim Shannon accuses the NI Secretary of engaging in a "love-in" with businesses and says she is "only seeking the opinion you want".
“If you don’t cast your net wider and seek opinions of other people, and stop seeking opinion of one blinkered opinion then you’re going to get a very rude awakening."
Karen Bradley says she isn't happy with every element of the deal but it's better than leaving without a deal. This is No10 talking - offering May's deal or no deal.
Shannon says he cannot support this.
Bradley says they will have to agree to disagree - but talks up the benefits of this deal.
Labour Brexiteer Kate Hoey asks how she felt when Shailesh Vara resigned as Northern Ireland minister last week over Brexit.
Karen Bradley said she was sad but she respects his position.
Hoey asks whether she raised it in cabinet but Ms Bradley refuses to comment on cabinet conversations.
She then moves onto the backstop, which starts to rile Bradley. She forcefully suggests that the backstop is subject to "mutual agreement" between the EU and the UK, and Northern Ireland cannot be split from the rest of the UK.
Hoey then cheekily refers to an interview Ms Bradley gave to the House, where she claimed she didn't know people in Northern Ireland voted on constitutional lines.
Bradley gets very cross and calls her "Miss Hoey".
Here's the piece we wrote on the row in September:
Kate Hoey says there is a perception that 'whatever the PM says you will go along with it', as part of a frosty exchange.
Former Conservative chancellor Ken Clarke has said he will back Theresa May’s Brexit plans when they comes to a vote in the House of Commons.
Mr Clarke said the deal to be signed off at a Brussels summit this weekend was not ideal, but that it delivered continuity for business and lay ground for critical future trade negotiations with Europe

Ms Truss told BBC Radio 5 Live's Emma Barnett Show: "If my colleagues in parliament don't vote for this then we're in grave danger of not leaving at all.
"I am very very worried about what the alternative looks like, because I'm a democrat. I believe that people voted in good faith to leave the EU and we need to deliver that."
Ms Truss said she was "confident we've got a good deal to send before parliament".
"The fundamentals are there, and the fundamentals deliver on what the people of Britain voted for which is the ending of free movement, being able to strike independent trade deals," she said.
Ms Truss said it was "a very, very serious moment for British politics", but denied the government was in crisis, saying: "No - the prime minister is very much in control of what's happening."
Jeremy Corbyn is on his feet. He welcomes AskHerToStand as well and says parliament must be more diverse.
He asks under what circumstances the UK could leave without a deal.
May says the alternative to her deal is uncertainty and no deal could risk no Brexit at all.
Corbyn says she did not answer the question whether it is a deal or not. He says its 'half baked'. He asks if it could be amended?
May says the withdrawal agreement is agreed but the future relationship is up for grabs.
Corbyn says the Brexit secretary post is 'entirely ceremonial' as May is going to Brussels rather than the new appointee Steve Barclay.
He says the withdrawal agreement does not cover the cost of extending the transition under the Northern Ireland backstop.
May says backstop is only insurance and will be superseded with a future trade deal.
Corbyn says a free trade deal will take a long time to agree with the EU and asks whether it will be ready by the end of December 2020?
May says his his problem with the deal is that he has not read it - referring to his comments on Sunday that he had not read all of it.
Huge cheers from the Tories when she attacks apparent inconsistencies in Labour's position and says Corbyn is 'playing party politics' with Brexit.
The Independent has launched its #FinalSay campaign to demand that voters are given a voice on the final Brexit deal.
