Following the crushing defeat last week of her agreement with Brussels, the Prime Minister will today make oral and written statements to the House of Commons explaining how she intends to proceed. Both groups say they will not back the deal unless the border backstop is removed.
May's spokesman James Slack said May's talks with opposition lawmakers were "genuine", and that a "significant number" had expressed concerns about the backstop. An open border was a key part of the 1998 Good Friday Agreement that brought an end to decades of conflict in Northern Ireland. He said public anger could trigger "a political tsunami".
Sky News reported that May is expected to set out plans to try and remove the Irish backstop, in an effort to win around the Northern Irish Democratic Unionist Party.
Polish Foreign Minister Jacek Czaputowicz on Monday floated putting a five-year time limit on the backstop, but Irish Deputy PM Simon Coveney immediately rejected the idea.
He told the Rzeczpospolita newspaper: "If Ireland asked the European Union to amend the agreement with the British on the backstop so that it would apply temporarily - let's say five years - the matter would be solved".
May risks losing control of the situation.
Britain's Brexit minister, Robin Walker, says the agreement is the first of its kind for Britain with a member of the European Union.
"Sympathy, patience and readiness to wait until the UK's position will be clarified are of utmost important to avoid the worst", warned Mr Altmaier. USA market is closed for the day owing to the celebration of Martin Luther King, Jr- day which makes London market hours the key active trading session for the pair today.
Al Jazeera's Laurence Lee, reporting from outside the House of Parliament in London, said it appeared May's strategy was "to run the clock down until March 29".
Mrs May attacked the Labour leader for refusing to take part in talks with her on the way forward.
Tensions within Labour have been rising as MPs who support a second referendum want to pressurise Corbyn into supporting another Brexit vote, in line with the party's policy to explore it as an option if it can not secure an early election. MPs will vote on the motions next week and if one or more pass, Ms. "And the European Union are very unlikely to extend Article 50 without a plan for how we are going to approve a deal".
On the highly contested matter of the Irish backstop, Theresa May said that she will hold further discussions with Northern Ireland's DUP and others negotiators about their concerns.
"We can not keep negotiating something this way and when everything is negotiated, the U.K. Parliament refuses", he said in Brussels. Rather than unveiling a Plan B, she set out Plan May with some procedural bells and whistles. "Crashing out in my view is an absolute disaster".
Residents and businesses on both sides of the 500-kilometre frontier also emphasise the importance of maintaining the free flow of trade and passenger traffic. "It's an absolute disaster for the country and it's supported by a minority of a minority of people".
She also repeated arguments against a second referendum - another people's vote on Brexit.
His amendment came as backbencher Yvette Cooper published her own separate, cross-party bill aimed at instructing Theresa May to delay Brexit by nine months if agreement can't be found before February 26.
It quoted an interview with Corbyn in which he said he would be opposed to any deal that would make the United Kingdom poorer, and then cited a report by the National Institute of Economic and Social Research that said "every form of Brexit will damage the United Kingdom economy".
"We need bold action", he was quoted as saying.
May's task is gargantuan: Convince the European Union to reopen negotiations and then secure enough changes to gain the support of at least 115 lawmakers who previously voted against the deal.
