British Prime Minister Theresa May intends to give parliament a second chance to approve a Brexit deal as soon as possible, her spokesman says, adding that negotiations to change the deal so it can win lawmakers' support were ongoing.
It is unclear how the political deadlock will pan out in Britain because her deal was previously voted down, by British MPs, and the European Union said it will not renegotiate the agreement she arranged with member states.
Brussels has repeatedly said it will not reopen the withdrawal agreement that May herself negotiated over almost two years, but the spokesman said it was clear it would never be accepted by the British parliament.
But the former foreign secretary said his support was dependent on the PM making clear she will demand legally-binding commitments on the controversial Irish "backstop" in the text of her Withdrawal Agreement.
He described the Brexit deal, which was agreed with the European Union but later fell flat in the House of Commons, as a "series of compromises" and said that it was designed around British red lines.
Britain's Prime Minister Theresa May speaks during a debate on her Brexit "plan B" in Parliament, in London, Britain, January 29, 2019, in this screen grab taken from video.
The Withdrawal Agreement May struck in November with the EU says the United Kingdom will remain in a customs union "unless and until" "alternative arrangements" are found to avoid a hard border.
Britain is heading for a new showdown with the European Union after United Kingdom lawmakers ordered Theresa May to return to Brussels and reopen her hard-won Brexit deal.
If the the Prime Minister fails again, then the chamber wants her to seek permission from European Union leaders to delay Brexit beyond the scheduled departure date of March 29.
A sizeable Labour rebellion had been expected for several days, despite the efforts of Cooper to calm concerned MPs in her party by telling the Commons it only gave parliament the right to vote on whether to extend article 50 if time ran out.
Top of the list is an overhaul of the back-up plan for the Irish border. "Today we need to send an emphatic message about what we do want". Parliament has expressed a desire to stop no-deal - but I am concerned that without legislation in place its probability has increased.
Earlier, the Commons rejected a bid by Jeremy Corbyn to force a debate on Labour's Brexit plans.
Labour will not formally say if it will order its MPs to back the plan until House of Commons Speaker John Bercow announces which amendments have been chosen for consideration on Tuesday morning, but three people familiar with the leadership's thinking said it was minded to support it.
Increasing numbers of government ministers have warned they will not accept the prospect of Britain leaving without a deal on March 29, immediately severing all ties with its largest trading partner and threatening economic chaos.
The amendment: A proposal aimed at getting May back to Brussels to renegotiate the Irish backstop has been submitted by Conservative backbencher Graham Brady.
A new proposal submitted by Conservative legislator Graham Brady commits to backing Mrs May's deal if the backstop is replaced by "alternative arrangements".
But the European Union has said that no deal means a hard border, of some kind.
That said, the next step in the Brexit process will depend on how the votes turn out later so we could either see a significant change to the current arrangement or it could lead to no changes at all.
And Ireland's Europe minister Helen McEntee called for "realism" from London.
