Labour, Tory rebels and the other opposition parties are now in the drivers seat as they threaten to bring down the entire Government.
May is heading to Brussels today after emerging from a confidence vote by Tory MPs bloodied and bruised but victorious.
The Prime Minister will address EU leaders at the two-day European Council.
Her position remains very shaky however as 117 MPs – more than on third of her party – voted against her last night.
Corbyn has said the vote makes “no difference” and described her government as “in chaos”.
“[The] government is in chaos and she is unable to deliver a Brexit deal that works for the country”
Labour leader Jez said: "Tonights vote makes no difference to the lives of our people.
“The Prime Minister has lost her majority in parliament, her government is in chaos and she is unable to deliver a Brexit deal that works for the country and puts jobs and the economy first.”
He said the prime minister was trying to avoid the vote on the “botched” and “dismal” deal – and urged parliament to “take back control”.
Mays latest troubles came after she pulled the “meaningful vote” on her deal from the Commons at the 11th hour – sparking fury across the House.

Corbyns number two – shadow chancellor John McDonnell – hinted that Labour could call the motion next week.
He warned the vote could come if May does not get changes to the Withdrawal Agreement.
Speaking on ITVs Peston, he said: "We will just have to judge what she comes back with on Sunday night, Monday morning, see what the statement is in the House of Commons on Monday and take a proper judgment then."
May's victory in the confidence vote means that another challenge cannot be mounted against her position as Tory leader for a year.

Former Conservative leader Iain Duncan Smith called on Theresa May to "engage" with her hard Brexit critics and "resolve" their concerns over the backstop by threatening to withhold the UK's £39 billion divorce payment to the EU.
"We cannot go on just with the idea that a fiddle here and a fiddle there is what the problem is," Mr Duncan Smith told BBC Radio 4's Today programme. "A compromise is there but it's the backstop which has to be resolved."
He urged the Prime Minister to "say to the EU now 'your £39 billion is fully at risk. We are not committed to the £39 billion unless we get some resolution'.
"They know that this backstop can be completely replaced by an open borders policy. Push them to the point where they recognise they have to do that and it resolves everything."

The PM will travel to the Belgian capital still faced with the same dilemma she faced before the no-confidence crisis.
She will be looking to convince the EU to tweak the Withdrawal Agreement so that it will be passed by Parliament
And this comes after May had said this was the “only deal” and said it could not be changed.
May has to bring her vote back to Parliament by January 21, just 67 days before Britain is due to leave the EU.
Despite the vote in her favour, Tory rebels such as Jacob Rees-Mogg have urged her to resign immediately.

Speaking in Downing Street moments after the result was announced, Mrs May acknowledged that a "significant" number of her MPs had voted against her and said: "I have listened to what they said."
She pledged to seek "legal and political assurances" on the Brexit backstop to allay MPs' concerns about her Withdrawal Agreement when she attends a European Council summit in Brussels on Thursday.
And she said she and her administration had a "renewed mission", saying: "Following this ballot, we now need to get on with the job of delivering Brexit for the British people and building a better future for this country."
She said this must involve "politicians of all sides coming together and acting in the national interest".
