Brexit effect. Boris Johnson resigns hours after David Davis

German Chancellor Angela Merkel arrived in London for a meeting with May and other leaders to discuss the Western Balkans.

In her resignation letter, Ms Caulfield warned that Mrs May's policy "may assuage vested interests, but the voters will find out and their representatives will be found out".

May's proposals should be used a jumping off point for further discussion, the official said, asking not to be identified because the talks are private.

Asked if the prime minister could survive.

"In his 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".

"I admit I stood shoulder to shoulder with DD to deliver Brexit & they annoyed the Europe Unit who are now running the show".

Some Conservative Brexit supporters are still incensed over what they see as her breach of a promise to break cleanly from the EU.

Meanwhile, Mr Johnson is said to be "keeping his powder dry" ahead of an expected challenge to Mrs May.

The plan has also caused outrage among eurosceptic members of May's Conservative party, and foreign minister Boris Johnson joined Davis in dramatically quitting this week in protest.

"I'm also committed to continuing the important work of supporting those affected by the Grenfell Tower tragedy and ensuring people are safe, and feel safe in their homes".

The Prime Minister is facing intense pressure to change course after a series of resignations - with two party chiefs following Boris Johnson and David Davis out of the door.

"The Queen has gladly approved Dominic Raab's appointment as a minister for Britain's release from the European Union", says the statement of the Theresa May's office. Mr Davis's deputy, Steve Baker, also resigned.

"I get along with her very well, I have a very good relationship". "And sending our best wishes to @England for tomorrow!"

But the timing of the announcement 15 minutes before the prime minister was due to give a press conference demonstrated that political niceties have been discarded, and will raise fears in Downing Street that there could be more to come.

Raab will replace David Davis in the role, who resigned late on Sunday evening stating that he could not continue to support the Brexit policy.

The former Brexit secretary said the latest United Kingdom government white paper would make the "supposed control by parliament illusory rather than real". "The only way we could remain members of the European Union is to reapply on certainly very unfavourable terms".

He said: "When it comes to a vote sometime around the end of this year, let us say that Theresa May has done a deal that bears some resemblance to what was put forward at Chequers with the EU". Both fiercely criticised her negotiating stance.

Widdecombe, well-known in Britain as being characteristically blunt, served in government under Prime Minister John Major, and in opposition under William Hague, where she was frequently tipped as a future party leader.

Tory former minister Mark Francois said a confidence vote in the PM was not the "right thing to do".
