(fashion) Tory Remainers were left furious after Boris Johnson cancelled a crunch meeting with 21 Brexit rebels.
'Peace talks' between Mr Johnson and a Remain Tory MP over No Deal Brexit scheduled for tomorrow was cancelled, a source revealed.
Government sources said the meeting between the PM and former justice secretary David Gauke was shelved due to 'diary issues'.
The prime minster is due to hold 'peace talks' with rebel Tory Remainers such as Mr Gauke, who vowed to vote against No Deal despite the threat of deselection by the party at a future general election.
A one-on-one meeting with Mr Johnson has been also offered to former chancellor Philip Hammond, sources added.
Boris Johnson gathered his closest aides at Chequers today as he braces for all-out war with Remainers in Parliament this week.
The PM, government whips and key officials - including maverick No10 chief Dominic Cummings - holed up for lunch at the country residence.
The tactics discussion came amid threats that Tory rebels who join cross-party efforts to stop No Deal in the coming days will be expelled from the parliamentary party.
Mr Johnson warned today that MPs had a 'fundamental choice' between his ambitious agenda, including pumping billions of pounds into public services, or the hard-left Labour leader.
He will hold showdown talks tomorrow with high-profile Conservative opponents of No Deal, including former Cabinet minister David Gauke.
Mr Gauke said this morning that he would be demanding to know how Mr Johnson proposed to get concessions from the EU, and whether there was even time left to ratify a deal if he gets one. He also made clear he is ready to sacrifice his career to stop the country crashing out.
The meeting will kick off a frenzied week in Parliament that could decide the fate of the UK.
MPs are set to try to seize control of the Commons agenda to pass a law stopping the country from crashing out of the EU, with the votes looking nailbitingly close.
Downing Street has heaped pressure on 'deceitful and underhand' MPs plotting to thwart the PM's plans.
Michael Gove caused fresh fury today by refusing to say whether the government would obey a law ruling out No Deal.
'Let's see what the legislation says,' he told the BBC's Andrew Marr Show.
As the rhetoric ramped up, Mr Johnson told the Sunday Times: 'I just say to everybody in the country, including everyone in parliament, the fundamental choice is this: are you going to side with Jeremy Corbyn and those who want to cancel the referendum?'
'Are you going to side with those who want to scrub the democratic verdict of the people - and plunge this country into chaos.'

Asked about his meeting with Mr Johnson, Mr Gauke told Sky News's Sophy Ridge programme: 'I want to hear from him as to what is his plan to deliver a deal.
'When are we putting forward proposals to deal with this backstop issue? 'And, I want to hear how he plans to deliver the legislation if we get a deal by October 31, because at the moment, frankly, I can't see how he's got time to do that.'
The Commons returns from summer recess on Tuesday, when Remainers are set to try to seize control of the parliamentary agenda to push through legislation that would force the PM to seek a Brexit extension from Brussels beyond October 31.
Mr Johnson has solemnly vowed to take the UK out of the EU by Halloween with or without a deal.
Leader of the Commons Jacob Rees-Mogg launched a vicious attack on the plotters today.
He told The Mail on Sunday: 'They dare not use the confidence procedures because they know that Jeremy Corbyn is too unpopular, and therefore they seek deceitful ends by underhand means.'
Reports that any bid to extend Brexit to stop a no-deal exit would be treated as a no confidence issue, with supporting Tory MPs stopped from standing for the party, drew a harsh response from Mr Hammond.

The ex-chancellor tweeted: 'If true, this would be staggeringly hypocritical: 8 members of the current cabinet have defied the party whip this year.
'I want to honour our 2017 manifesto which promised a 'smooth and orderly' exit and a 'deep and special partnership' with the EU. Not an undemocratic No Deal.'
Mr Gauke also dismissed the threat.
'Sometimes there is a point where... you have to judge between your own personal interests and the national interest,' he said.
'And the national interest has to come first.
'But, I hope it doesn't come to that, and I
