Conservative MP Nick Boles risking deselection over his bill to rule out no deal
"This bill is about creating the space for a compromise by ruling out a no-deal Brexit," he told the BBC.
To pass his new bill, Mr Boles will need to suspend the rules in Parliament so that he does not need government support to free up parliamentary time for it.
He could do this by amending the government's business motion which sets out the schedule ahead of the Commons debate on 29 January.
He told the Political Thinking podcast: "We have had indications that many ministers, including cabinet ministers are very, very keen to see it pass and are telling the prime minister that they will not vote against it.
"There is a bandwagon rolling, it's got a lot of momentum behind it and I very much hope that any MP who shares my view that a no-deal Brexit would be a disaster, will jump on board.
"I have been told directly by ministers, not in the cabinet, that they have said that they would resign if they are whipped to vote against it."
While he did not know if any cabinet ministers would quit, he said the transcript reported in the Daily Telegraph of a conversation in which Philip Hammond "made quite plain that he thought this was fantastic".
What about the threat of de-selection?
Mr Boles said he would not change his view on Brexit to please a small number of Conservative members in Grantham and Stamford.
"One hundred people in my local party have written in saying they're outraged by what I'm saying and want to de-select me," he told the podcast.
"And the truth is that many of them used to belong to UKIP only about a year ago.
"They're entirely entitled to their view, they're entitled to be members of the Conservative Party and they're entitled to de-select me.
"But I am not going to change what I believe is in the interest of the 80,000 people that I represent in Parliament because of 100 people in my constituency party."
And worth also mentioning: Speaker Bercow could be the first speaker not to get a peerage for standing up to Ministers in allowing Parliament a meaningful vote
A reminder that, amidst all the gloom, there will be honourable MPs on both sides seeking to do the right thing. If the incompetent May won’t pursue a genuine compromise, and the cynically Eurosceptic Corbyn won’t support majority opinion in his own Party for a Peoples’ Vote (which with other Opposition Parties and dissident Tories probably has the numbers to pass if the only alternative is no deal), then the numbers should also exist for moderates on both sides to put together a cross party compromise. But the clock is ticking - hence the importance of the Boles bill.
