(fashion) Michael Gove risked escalating the raging Brexit row today by refusing to say whether the government would obey a law ruling out No Deal.
The Cabinet minister left open the prospect of ignoring legislation as the government and Remainers gear up for a titanic battle in Parliament this week.
Labour, the SNP, the Lib Dems and Tory rebels are trying to seize control of Commons business so they can push through a Bill demanding Boris Johnson seeks an extension from Brussels rather than allowing the UK to crash out on October 31.
But asked today if the PM would obey such a law, Mr Gove told the BBC's Andrew Marr show: 'Let’s see what the legislation says.'
He also accused pro-EU MPs of being in a 'denial of democracy'.
Mr Johnson, who has made a 'do or die' pledge to get the UK out of the EU by Halloween, today warned Tory rebels that derailing his Brexit plans risks condemning the country to 'chaos' with Jeremy Corbyn in power.
The PM said Remainers had a 'fundamental choice' between his ambitious agenda, including pumping billions of pounds into public services, or the hard-left Labour leader.
The stark ultimatum came ahead of showdown talks tomorrow between Mr Johnson and 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.
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.
And in an interview with the Sunday Times, Mr Johnson said: '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 hope cooler and calmer heads will look at this and think that trying to split the Conservative Party in this way is not a sensible way forward for the Conservative Party, or indeed for the country.'
A Government spokesman said: 'All options for party management are under consideration, but first and foremost the PM hopes MPs will
