MPs have dramatically rejected crashing out of the European Union without a deal at any time and under any circumstances.
If Mrs May's deal passes, the United Kingdom will leave the European Union under the terms of the deal on 29 March. The move sets up another crucial vote on Wednesday, in which MPs will decide whether to move forward with Brexit on March 29 despite the lack of a Parliament-approved agreement between the United Kingdom and the E.U. The outcome of that vote could then prompt a vote to delay Brexit.
He appealed for unity among MPs and the country, and rejected the notion of a no-deal Brexit: "We didn't vote to leave without a deal".
Some 75 Conservative MPs rebelled to vote against the deal, while just three Labour MPs and four independents joined the 235 Tories who backed it.
Mrs May agreed but insisted her deal is a "good deal" and she wants the United Kingdom to leave with a good deal.
"This fiasco can not go on - is absolutely clear that there must be an extension to article 50 to allow the public to vote again".
"If the deal is defeated tonight it is impossible to imagine that the prime minister would allow this to drift into next week, when Oliver Letwin will table a bill for the House of Commons to take over the negotiating process".
The EU's chief negotiator, Michel Barnier, has said the current impasse "can only be solved in the UK" and MPs must decide what they want rather than what they don't.
"What will their choice be, what will be the line they will take?" he asked.

Mrs Lewell-Buck said it is a good thing that we won't be leaving with the Prime Minister's deal, but they need to move forward now and get the best Brexit deal possible.
Downing Street has so far not laid out any groundwork for an extension. The discussion on Article 50 is done and dusted.
David Cameron has warned MPs that failing to rule out a no-deal Brexit would be a "disaster" for Britain.
60% of the public agrees that politicians "should compromise and agree on a Brexit deal that honours the referendum result".
Shadow business secretary Rebecca Long-Bailey told BBC News Parliament would increasingly "set the agenda" if the government was not in control of events.
She said: "It surprised me again as it did last time how major the loss was".
On Wednesday morning the government announced that most imports into the United Kingdom would not attract a tariff in the event of a no-deal Brexit.
"I think that's the conclusion MPs will ultimately come to".
Mr Zeichner slammed the government for "recklessly wasting yet more time in order to force a false binary choice" over Brexit.
