LONDON — Brexit-supporting rebels in British Prime Minister Theresa May's party said on Wednesday they would vote down her European Union divorce deal when she brings it back to parliament early next month.

Brexit had been due to take place on March 29 but lawmakers rejected the withdrawal agreement that May struck with Brussels three times. The United Kingdom is now scheduled to leave the EU by Oct. 31.

May will bring a Withdrawal Agreement Bill, which implements the departure terms, in the week beginning June 3 — the same date that US President Donald Trump begins a state visit to Britain at the invitation of Queen Elizabeth.

Brexit supporters in May's divided Conservative party said her deal was as dead as her crisis-riven three-year premiership.

"I have talked to colleagues, some of whom voted for it last time, and they think it is dead and they will vote against it this time," Peter Bone, a Conservative lawmaker and a prominent supporter of leaving the EU, told Talk Radio.

"I know they wouldn't vote for it. It seems absurd to bring it back. It is the same thing again, again and again."

May, who secured the Conservative Party leadership and the premiership in the chaos that followed the 2016 Brexit referendum, is already under pressure from some of her own lawmakers to set a date for her departure.

Defeat in the June vote would likely spell the end of her divorce deal and her premiership.

Brexit supporters fear that May's deal will keep the United Kingdom trapped within the EU's orbit for years and that it could ultimately pull the British province of Northern Ireland towards the bloc.

Nearly three years after the United Kingdom voted 52% to 48% to leave the EU, politicians still disagree about when, how or even if the divorce will take place.

Before her deal was defeated the last time, 344-286 on March 29, May had promised to resign if it was passed. It was voted down first in January and again in mid-March.

A constant sticking point has been the Irish backstop, an insurance policy aimed at avoiding post-Brexit controls on the border between Northern Ireland and EU state Ireland.

"If the Prime Minister brings the Withdrawal bill to the Commons for a vote the question will be 'what has changed?'" asked Nigel Dodds, parliamentary leader of the Northern Irish Democratic Unionist Party (DUP), which props up May's minority government.

"Unless she can demonstrate something new that addresses the problem of the backstop then it is highly likely her deal will go down to defeat once again," Dodds said.

A majority of members of the European Research Group, a large Brexit-supporting faction in the Conservative Party, will vote against May's deal, said Owen Paterson, a former minister.

"Sadly, we will vote against it again," he said, adding that it could divide the country. — Reuters
