Theresa May insists it’s her deal or NO Brexit as Remain MPs launch ‘bullet-proof plan to sink EU exit’

The panel of senior backbenchers would then be responsible for drawing up any new Brexit legislation.

Insiders told The Times it will involve delaying or even REVOKING Article 50 if Parliament can't find a way forward.

Asked whether Theresa May was concerned about backbench Tory Nick Boles' proposal for Parliament to take control of the Brexit process, the PM's official spokesman said: "Any attempt to prevent the Government from meeting all the legal conditions for an orderly exit at this moment of historic significance is extremely concerning."

As Mrs May tries to face down the rebels:

• She has published a letter from Eurocrats providing assurances over the Irish backstop - and saying it's only temporary
• A dozen senior Tories urged colleagues to vote down the deal tomorrow
• EU officials said they were ready to postpone Brexit thanks to the ongoing chaos
• Labour threatened to hold a vote of no confidence in Mrs May this week

The Prime Minister is warning that a second referendum is now more plausible than a No Deal outcome thanks to Parliament's machinations.

A Cabinet minister the backbench coup was a “copper-bottomed, bullet-proof plan to sink Brexit which relies on the fact that Government has no majority and that the Speaker will bend the rules.”

A draft Bill, drawn up by former ministers Nick Boles, Nicky Morgan and Sir Oliver Letwin, is to be published this afternoon.

It would allow MPs to seize control of what laws can be put before the Commons if Mrs May is defeated tomorrow.

Mr Boles told the BBC: "This bill would do the following: it would give the Government three more weeks to get a compromise deal, a plan B, through Parliament so that we are leaving the EU on time on March 29 with a deal.

"If that failed, it would then ask the Liaison Committee, which is the committee of all the chairs of select committees and other parliamentary committees, it would give the Liaison Committee the responsibility to try and come up with its own compromise deal, which would have to go back to the House for a vote.

"If the House passed that compromise deal, then the Government would be legally required to implement whatever it was that they had."

The committee comprises the chairs of the 36 Commons select committees, of whom 27 backed Remain and just nine Leave.

But Mr Boles denied that the move represented a pro-Remain coup, saying: "It's a funny kind of coup which requires a majority vote of democratically-elected MPs before the task start rolling.

"So, no, it isn't a coup, it's an expression of parliamentary will."

But the plan was dismissed by some members of the Liaison Committee - arch-Remainer Sarah Wollaston said: "Backbench MPs cannot take over conducting a complex international negotiation."

Her deputy Pete Wishart also refused to play a part in it.

A separate group of pro-EU politicians have today published a draft law which could make a second referendum a reality as early as this week.

The Lib Dem and SNP leaders teamed up with senior Tory and Labour MPs to draw up the legislation in secret over the past few months.

The bill, written by parliamentary experts, is designed to provide an off-the-shelf way of enshrining a second referendum into law.

It would see Article 50 delayed to allowed time for a so-called "people's vote" to take place some time between April and July.

The cross-party group hopes to convince Jeremy Corbyn to back the bill as soon as this week, a source told The Sun.

Rebel ringleader Dominic Grieve said: "With no majority in Parliament for the deal, or for No Deal, the legislation provides the Government with an escape hatch."

Lib Dem boss Vince Cable added: "This bill puts flesh on the bones of our campaign for a final say. Crucially, it shows how quickly a people's vote can be delivered."

On the other side of the debate, Brexiteers are tabling an amendment which would limit the duration of the hated "Irish backstop" to no more than a year.

Tory MP Andrew Murrison said: "The amendment I am tabling will address the concerns I have heard expressed by a large number of colleagues across the House about the potential 'forever' nature of the backstop.

"It will introduce a sunset arrangement by which the backstop will fall away."

It has been claimed EU leaders are preparing to delay Brexit until July or possibly longer if Parliament cannot agree a deal.
