MPs rejected her divorce deal by a majority of 149, despite the Prime Minister attempting to convince Westminster she had secured legal concessions from Brussels. Some 75 Tory rebels blocked her improved deal, down from the 118 who voted down her Withdrawal Agreement in January. Speaking after the result was announced, Mrs May said she “profoundly regrets the decision this House has taken tonight”.
The Prime Minister added: “I continue to believe that by far the best outcome is the UK leaves the EU in orderly fashion with a deal.
“And that the deal we have negotiated is the best and indeed only deal available.”
The Northern Irish DUP, whose 10 votes prop up the Government, voted against the deal, along with many members of the European Research Group (ERG).
On a day of high drama in Westminster, the Prime Minister earlier warned MPs that “Brexit could be lost” if her divorce deal was defeated.
MPs rejected Theresa May’s Brexit deal tonight
Mrs May urged MPs to get behind her plan, claiming she had secured legal changes to the backstop following her 11th hour trip to Strasbourg last night.
But momentum shifted against Mrs May when Attorney General Geoffrey Cox refused to make a U-turn on his legal advice that the UK could be permanently trapped in the backstop arrangement.
Mr Cox said that while the risk was reduced it could not be ruled out.
MPs are now expected to vote to block a no-deal Brexit tomorrow and to delay the UK’s departure from the EU on Thursday.

7.30pm update: EU responds to Withdrawal Agreement defeat
The EU has responded to tonight’s defeat, with European Council president Donald Tusk saying he was “disappointed” by the result.
A spokesman said: “We regret the outcome of tonight’s vote and are disappointed that the UK government has been unable to ensure a majority for the Withdrawal Agreement agreed by both parties in November.
“On the EU side we have done all that is possible to reach an agreement. Given the additional assurances provided by the EU in December, January and yesterday, it is difficult to see what more we can do. If there is a solution to the current impasse it can only be found in London.
“The EU for its part continues to stand by the Withdrawal Agreement, including the backstop, which serves to prevent a hard border in Ireland and preserve the integrity of the single market unless and until alternative arrangements can be found.
“With only 17 days left to 29 March, today’s vote has significantly increased the likelihood of a ‘no-deal’ Brexit. We will continue our no-deal preparations and ensure that we will be ready if such a scenario arises.
“Should there be a UK reasoned request for an extension, the EU27 will consider it and decide by unanimity. The EU27 will expect a credible justification for a possible extension and its duration. The smooth functioning of the EU institutions will need to be ensured.”
