Theresa May's husband is accused of scuppering attempts to reach out to Labour MPs ahead of critical Commons vote after urging the PM to keep fighting for her Brexit deal
- The PM's husband, Philip May, has been dragged into the bitter Brexit fighting
- Mr May urged his wife not to cave into demands to get a cross-party compromise
- No10 chief of staff Gavin Barwell allegedly 'flamed' Mr May over the intervention
Theresa May's husband was dragged into the Brexit civil war at No10 today amid claims he urged the PM not to cave in to Labour demands for a permanent customs union.
Philip May apparently enraged senior aides by instead backing a new push for a deal with Brussels that would finally win over Tory rebels and the DUP.
The spat emerged as tensions escalate dramatically over how to resolve the deepening political crisis over Brexit.
Mrs May is facing another frantic week as she tries to keep her Cabinet together and fend off a bid by cross-party Remainers to force her to delay the Article 50 process.
If the plan, pushed by Labour's Yvette Cooper, is passed by MPs on Tuesday it would pave the way for law ordering a nine-month extension to be considered on February 5.

Amendments are also tabled intended to rule out a no-deal Brexit, and stage a series of 'indicative' votes to work out what approach would gain a majority in the Commons.
The government seems to be pinning its hope on changes tabled by senior Tories that would demand a rewriting of the controversial Irish border backstop - something she could take to Brussels as concrete evidence of the will of MPs.
But according to the Sunday Times there was a major meltdown in No10 over whether to try to get a deal through with support from Labour.
No.10 chief of staff Gavin Barwell apparently accused Philip May of 'scuppering' plans to offer the Opposition a permanent customs union with the EU.
A source said: 'Philip May was flamed by Barwell for scuppering the outreach to Labour.'
Mrs May's husband lined up with chief whip Julian Smith, who warned that ignoring the objections of Brexiteers and the DUP risked tearing the Tories apart.
The PM has made clear she is determined to renegotiate the controversial Irish border backstop in a bid to win over critics of her package.

But Mrs May must control rising unrest in her own ranks, after Amber Rudd hinted she could quit to support the Cooper amendment on Tuesday.
Chancellor Philip Hammond also refused to rule out resigning if the government's stated policy becomes no deal Brexit - although he tried to play down the idea that the votes this week are 'high noon', saying there was still time to find a solution.
Cabinet Office minister David Lidington, the PM's effective deputy, today pleaded for Remainer MPs to hold their far, saying there would be other opportunities to avoid no deal.
'If Parliament wishes to avoid no deal, I have no doubt it will find ways to express a view in the coming weeks,' he wrote in the Observer.
'But next week's debate is not a re-run of the meaningful vote, nor is it the final decision point for MPs.
'So we must keep our focus on the only real way to rule out no deal - and that is to find common ground on a deal.'
Defence minister Tobias Ellwood today openly contradicted the PM by warning it is 'time to rule out the very possibility of no deal'.
'It is wrong for government and business to invest any more time and money in a no-deal outcome which will make us poorer, weaker and smaller in the eyes of the world,' he wrote in the Sunday Times.
However, Education Secretary Damian Hinds said no deal could not be taken off the table.
He made clear it was not his favoured outcome, but warned that 'prolonging' the Article 50 period would not help resolve the crisis.
'I don't envisage no deal becoming Government policy. 'We want to avoid a no deal. No deal would not be a good outcome,' he told Sky News' Sophy Ridge On Sunday.
'But, it is important that it remains as a possibility because, on the other hand... some people are trying to thwart Brexit altogether.'
Speaking on the BBC's Andrew Marr Show, Ms Cooper denied she was trying to 'block Brexit' with her amendment.
The former Treasury minister said she was not yet sure if she had the backing of Labour leader Jeremy Corbyn, nor of some of the Tory frontbench. On Mr Corbyn she said: 'I hope he will support it - he obviously needs to make a decision in the normal way.
'I suppose what I would say to him, to the Prime Minister, to the Government ministers who I think also want to make sure that we don't have no deal is in the end we can't... keep waiting for other people to sort this out.
'We can't carry on with a kind of game of chicken... That's not a way to make sensible decisions.
'In the end someone has to take some responsibility and say: 'if the Prime Minister runs out of time she may need some more time' - that is not about blocking Brexit, that is about being responsible and making sure you can get a Brexit deal.'
It comes after reports preparations are being looked at for the possible imposition of martial law after a no-deal Brexit.
The move has been described by sources as the civil service 'prepping' for all possibilities.
A Downing Street spokesman said: 'Respecting the referendum decision means leaving the EU.
'The PM has said that there will be disruption in the event of no deal, but as a responsible Government we are taking the appropriate steps to minimise this disruption and ensure the country is prepared.'
As the political crisis gathers pace, the Government is ready to extend working hours for MPs in order to get Brexit legislation through the Commons before the scheduled EU withdrawal date of March 29.
Responding to news the Government was looking at the possibility of a martial law scenario, Labour MP and Best for Britain campaign supporter, David Lammy said: 'This is a full-blown crisis.

'The Government is recklessly drawing up plans for a colossal act of self-harm.
'Through continuing on the path to Brexit, despite having achieved no consensus on a deal in Parliament, the Government is preparing to declare war on itself.
'The idea that the Government has any mandate for this catastrophic scenario is ludicrous.
'The Leave campaign promised a stable new trading relationship with the EU after Brexit, not total isolation and soldiers in our airports.'
