'We do not agree' on Brexit plan with outgoing ministers: May

Lawmakers howled as a beleaguered May paid tribute to two senior members of her Cabinet who resigned rather than accept her proposals.

May's office said in a terse statement that the prime minister had accepted Johnson's resignation and would name a replacement soon. "The Prime Minister thanks Boris for his work".

Schinas said the bloc "will continue to negotiate in good will, bona fide, with Prime Minister Theresa May and the United Kingdom government negotiators in order to reach a deal".

British Prime Minister Theresa May dug in her heels Monday after the resignation of two top government ministers over Brexit negotiations whipped up a storm that threatened to topple her fragile minority government.

Theresa May will chair her new-look cabinet this morning after a string of resignations over her Brexit strategy left her government in crisis.

"In a resignation letter, Davis said the "'common rule book' policy hands control of large swathes of our economy to the European Union and is certainly not returning control of our laws in any real sense".

Opposition politicians were quick to capitalize on May's troubles.

Labour MP Andrew Adonis said Raab's appointment could spell the "death" of the Tory leader, while writer and editor Hitcham Yezza said Brexit has now become even more "shambolic".

Last Friday at the prime minister's country retreat at Chequers My May brokered a "collective" agreement on proposals for the future relationship between the European Union and UK. Jacob Rees-Mogg, who leads a bloc of Brexit-supporting Conservative MPs in Parliament, urged May to give up on the plan.

When asked whether May would contest any vote on a confidence motion in her leadership, her spokesman said: "Yes".

"If the Brexit deal is rejected by Parliament, then we, the people of Britain, should have the democratic right to determine our own future".

Instead May was tonight scrambling to shore up her ailing Premiership amid fierce rumours she is set to face a no confidence vote, possibly within hours. There was feverish speculation on Monday about May's prospects.

Long before the Brexit referendum and its aftermath, the Conservative Party was split on Europe, and May has struggled to unite the warring wings under her leadership.
