Labour has joined with MPs from other parties, including senior Conservatives, to launch a fresh bid to block a no-deal Brexit. The party will force a vote on Wednesday on a motion to stop the government taking Britain out of the EU without an exit deal.
The news came shortly after the EU dismissed Tory leadership candidates’ claims that they will be able to renegotiate Theresa May’s deal. A spokesperson for the European Commission insisted the bloc would “not change the parameters of what is on the table”.
Boris Johnson picked up further endorsements from Tory Brexiteers to succeed Ms May. Launching his leadership bid on Tuesday evening, Rory Stewart attacked the credentials of Mr Johnson and jokingly compared him to a “prancing elephant”.
"As prime minister I would propose to put my plan, which I have already published, to the House of Commons, in principle, immediately and therefore show the European Union that this plan is deliverable through the House of Commons."
He insisted the EU could agree to put a time-limit on the controversial Northern Ireland backstop, despite it having said repeatedly that it will not.
He claimed:
"They nearly proposed a time limit on the backstop before, but they didn't think that the prime minister, Theresa May, would be able to get it through the House of Commons."

Frontrunner also accused of a Brexit plan that would ‘annihilate’ party and put Jeremy Corbyn in power ‘by Christmas’, and of ‘hiding’ from scrutiny"The deficit is at last under control, austerity is over and we can start to invest again."
"In all circumstances, we are leaving the EU on 31 October this year. Our country and our party cannot afford any more indecisiveness."I do not think that parliament has the ability to prevent us leaving at the end of October."
"Of all the candidates, I am the one who will not be withdrawing under any circumstances. I think we have tested that to destruction over the last three years. If I come second, I am absolutely going all the way."
"Everyone else in this race has at some point in the last three years been sat around the cabinet table and has participated in the decisions that have led to us not leaving the EU three years after the referendum. Everyone single one of them has participated in the fundamental misjudgements that have got us to where we are."
"It's not going to be possible to leave on 31 October... It's not credible to say you can renegotiate the withdrawal agreement and get it through both houses of parliament by 31 October. It's not credible to say you can somehow make parliament to vote for the existing, unchanged deal by 31 October."
"It's obvious to me that some of the choices set out by other candidates I don't think are the right choices... I want to focus tax cuts on people at the lower end of the spectrum... I don't think we should be making promises we can't keep."
"I think you have to be prepared to set out your stall and open yourself to questioning. You have got to level with people about the challenges and be prepared to be questioned about it."
"I think all candidates in this race owe the public clear answers. I haven't taken any illegal drugs in my entire life. I come from a background where people didn't do that sort of thing. I don't get invited to those sorts of parties and I don't hang out in those sorts of circles."
"I think we should all answer questions like this, if you want to be prime minister. If are not prepared to answer these questions now, you are going to be asked them in a general election campaign. If I'm a Conservative MP in a marginal constituency, I want the person who's going to be leading my party to answer these questions now, I don't want them to be answering these questions in three years' time when it's my marginal constituency up for grabs. Everyone has to answer these questions and then my colleagues will ask questions about how frank we've been. If you have got nothing to hide, you won't mind answering questions."
