Theresa May is heading to Brussels for an EU summit, the morning after surviving a vote of confidence, report agencies.
The prime minister is seeking legally binding pledges from EU leaders on the Irish backstop – a key obstacle for MPs who oppose her Brexit deal.
The EU will not renegotiate the deal but may be willing to give greater assurances on the temporary nature of the backstop, the BBC understands.
The PM won the ballot on her leadership by 200 votes to 117 on Wednesday night.
The secret ballot was triggered by 48 of her MPs angry at her Brexit policy, which they say betrays the 2016 referendum result.
Speaking in Downing Street after the vote, Mrs May vowed to deliver the Brexit “people voted for” but said she had listened to the concerns of MPs who voted against her.
But Liberal Democrat leader Vince Cable said, despite the “high drama” of Wednesday, “nothing has really changed”.
Former Tory leader Iain Duncan Smith said it was now up to Mrs May to listen to her party and “push the EU… to resolve the backstop”.
Earlier this week, the prime minister travelled to meet EU leaders, including German Chancellor Angela Merkel and Dutch Prime Minister Mark Rutte, to raise the issues surrounding the withdrawal agreement at Westminster one-on-one.
But a trip to meet the Irish Taoiseach Leo Varadkar had to be cancelled because of the leadership vote. At Thursday’s summit, Mrs May will have an opportunity to spell out face to face the problems to all leaders of the 27 member states. The EU leaders will then consider what could be done – without Mrs May in the room. Theresa May will front up in Brussels later – still the Prime Minister, still officially in charge.
One cabinet minister last night told me the whole challenge to her had been “futile”, suggesting it hadn’t really changed much.
But it really has. Theresa May has a temporary shield from another direct call for her departure from her own MPs . Angry Brexiteers can’t try to move her out for another year in the same way. That on its own is a sigh of relief certainly for her supporters, claiming a “good result” last night.
But that does not remotely protect her from the brutal reality that she right now, has no workable Brexit policy that can make it through the Commons.
The BBC understands that any reassurances offered to Mrs May could centre on an attempt to “detoxify” the idea of the backstop for Westminster, says the BBC’s Europe correspondent Kevin Connolly.
He said its temporary nature could be emphasised, along with the EU’s readiness to keep searching for a better alternative even if the backstop
were ever to be triggered – both stronger reassurances to the policy’s critics than offered in the past.
For example, a draft of the European Council conclusions on Brexit says the EU would use its “best endeavours to negotiate and conclude expeditiously a subsequent agreement that would replace the backstop so that it would only be in place for a short period and only as long as strictly necessary.”
In other words, the EU would continue trying to negotiate a trade deal with the UK even if the Irish backstop had been triggered at the end of the transition period.
The Brexit withdrawal agreement only talks about “best endeavours” being used to reach an agreement during the transition period.
But the BBC’s Brussels reporter Adam Fleming says the draft put forward by the European Council could be subject to change.
Westminster critics of Mrs May’s Brexit deal might also complain that it is not legally binding.
However, the core message from Brussels remains that there will not be a renegotiation of the withdrawal agreement whatever happens, even if the Conservative Party had changed its leader.
This was reiterated by the President of the European Commission Jean Claude Juncker who, in a phone call with Mr Varadkar on Wednesday, said that the deal on the table was “a balanced compromise and the best outcome available”, and “cannot be reopened or contradicted”.
Mr Duncan Smith, a Brexiteer who voted against Mrs May on Wednesday’s vote, said he wanted to “send a strong message” to the PM.
He told BBC Radio 4’s Today programme: “We cannot go on just with the idea that a fiddle here and a fiddle there is what the problem is.”
Instead, he said Mrs May should say that the £39bn the UK has agreed to pay the EU as part of the divorce deal is “at risk”.
“They have got to say to the EU… we are not committed to this £39bn unless we get some resolution”.
Mr Cable, who is also against the deal, told BBC Breakfast: “We are still back with the problem that the government has a proposal that we can’t get through Parliament and we have got to try and break that gridlock.”
He called on Labour leader Jeremy Corbyn to “come off the fence” and back another public vote on Brexit.
Mr Corbyn last night agreed that nothing had changed and that the government was in “chaos”.
Labour has said that it will table a no-confidence motion that all MPs – not just Conservatives – will be able to vote in when they felt they had a chance of winning it, and forcing a general election.
But the DUP – which props up Mrs May’s government – said it would not support such a motion at this stage.
The prime minister won the confidence vote with a majority of 83 – 63% of Conservative MPs backing her and 37% voting against her.
Her supporters urged the party to move on but critics said losing the support of a third of MPs was “devastating”.
The BBC’s Laura Kuenssberg said the level of opposition was “not at all comfortable” for the prime minister and a “real blow” to her authority.
A split was still clear in the Tory Party after the result. Jacob Rees-Mogg, who led calls for the confidence vote, said losing the support of a third of her MPs was a “terrible result for the prime minister” and he urged her to resign.
But Nicholas Soames urged Brexiteers to “throw their weight” behind the PM as she sought to address the “grave concerns” many MPs had about aspects of the EU deal.
DUP deputy leader Nigel Dodds said his party was also still concerned about the Irish backstop plan, telling BBC News: “I don’t think this vote really changes anything very much in terms of the arithmetic.”
