Theresa May will meet European leaders and EU officials later for talks aimed at rescuing her Brexit deal.
She will hold talks with Dutch PM Mark Rutte and Germany’s Angela Merkel after postponing MPs’ final vote on the deal.
The UK PM has said she needs “further assurances” about the Northern Ireland border plan to get Commons backing.
European Council President Donald Tusk insisted the EU would “not renegotiate” but said leaders would discuss how to help “facilitate UK ratification”.
Work and Pensions Secretary Amber Rudd said further talks with Brussels would focus on the Brexit “backstop” on the Irish border, which Mrs May earlier admitted had caused MPs “widespread and deep concern”.
The PM’s abrupt U-turn – after days of repeated insistence that the vote would go ahead – prompted Labour leader Jeremy Corbyn to secure a three-hour emergency debate on Tuesday.
“It cannot be right that the government can unilaterally alter the arrangements,” said Mr Corbyn, who earlier accused Mrs. May of “losing control of events”.
Leading Conservative Brexiteer Jacob Rees-Mogg said in a statement that Mrs. May lacked the “gumption” to put her “undeliverable” deal before MPs.
Labour leader Jeremy Corbyn had been hoping to force a general election if Mrs. May had lost Tuesday’s planned vote, by tabling a vote of no confidence.
In his reaction to Mrs. May’s announcement that the vote would be delayed, he urged the PM to stand down because her government was now in “chaos”.
But Labour has rejected calls from the SNP, the Lib Dems and some of its own MPs, to hold a vote of no confidence in the prime minister on Tuesday.
A Labour Party spokesperson said it had more chance of success when the deal came back before MPs.
However, Labour will seek to keep the pressure on the PM in an emergency debate in the Commons – which was granted after MPs were denied a say in the cancellation of Tuesday’s vote.
