The Secretary of State for Exiting the European Union has resigned last night in a letter to the Prime Minister amid conflicts over Number 10’s “Common Rule Book”.

Agreed on Friday, the “Common Rule Book” would create a free trade area for industrial and agricultural goods with the European Union.

In his letter to Theresa May, David Davis said the consequences of the policy would leave Parliament's control “illusory”.

He said: “I have disagreed with the Number 10 policy line, ranging from accepting the Commission’s sequencing of negotiations through to the language on Northern Ireland in the December Joint Report.

“The Cabinet decision on Friday crystallised this problem.

“In my view the inevitable consequence of the proposed policies will be to make the supposed control by Parliament illusory rather than real.”

Dominic Raab has been appointed as the new Secretary of State for Exiting the European Union.

After Mr Davis's resignation Pro-Brexit MPs hit out at the government, igniting fears of a possible leadership challenge.

They see the Government's new approach as capitulating to the EU's demands.

David Davis finished his resignation letter by questioning the PM’s approach to the negotiations calling himself a “reluctant conscript.”

He said: “I am also unpersuaded that our negotiating approach will not just lead to further demands for concessions.

“The national interest requires a Secretary of State in my Department that is an enthusiastic believer in your approach, and not merely a reluctant conscript.

“While I have been grateful to you for the opportunity to serve, it is with great regret that I tender my resignation from the Cabinet with immediate effect.

“Yours ever, David Davis”

Bambos Charalambous MP for Enfield and Southgate said: "I can’t say I’m surprised - Theresa May’s government just limps from crisis to crisis.

"They’ve now had two years since the referendum to sort out their Brexit position and this absolute chaos proves why the Tories lost their mandate last year.

"We need a Labour government as soon as possible to negotiate on behalf of everyone."
