Theresa May is facing a fresh Remainer onslaught after she finally won backing from ministers for her Brexit blueprint.
The Prime Minister is facing a serious threat to her plans as Tory rebels unite with Labour, the Lib Dems and SNP to try to force the government to stay inside a customs union.
Former minister Anna Soubry has tabled an amendment to the Trade Bill that could put Mrs May’s slim Commons majority to the test.
But Downing Street today made clear they would not cave in in the crucial issue, paving the way for a showdown in parliament.
Meanwhile, Brussels has slammed her proposals for future trade ties, agreed by the Brexit war Cabinet last night, saying it will not allow the UK to pick and choose what regulations it follows.
No10 has confirmed that the premier will make a major Brexit speech on Friday as negotiations reach a critical stage.
After eight hours of discussions, the Brexit war cabinet reached an agreement.

After eight hours of talks at the Prime Minister’s country retreat Chequers, senior ministers agreed to pursue a strategy that will allow the UK to diverge from EU laws.
Pro-Brexit ministers claimed they had achieved a significant step in ensuring a clean break with the EU – with one senior figure describing it as an ‘outbreak of unity for now’.
One Cabinet source said: ‘Divergence has won.’
But, in a concession to pro-Remain ministers, the pace and scale of any future divergence is likely to be fudged for months.
Ministers, who did not leave chequers until 10pm, were tight-lipped about the precise details of yesterday’s meeting.
According to the BBC, one minister in the room claimed everyone was ‘rather happy’ at the end, with another saying the PM had ‘played a blinder’.
Another said they had reached a ‘sensible compromise which pitches an ambitious ask but recognises that we will be in a negotiation’.
Sources said they had agreed to seek an ambitious deal that would allow wide-ranging access to the single market for British goods and services on the basis of ‘mutual recognition’ of standards rather than membership of the customs union.
In return, Britain would make a binding declaration not to undercut the EU by leading a ‘race to the bottom’ on workers’ rights.
Within this framework, Britain would have the ‘right to diverge’ from EU laws – particularly in emerging technologies like artificial intelligence.
But the proposals have been dismissed by the EU before being formally tabled. One diplomat told the Evening Standard: ‘We cannot make sense of all the ideas they have floated because lots of them are inconsistent.’

Asked about the UK’s proposals for a trade deal as he arrived at a summit in Brussels today, Mr Juncker said: ‘I’m not the British Prime Minister. It would be good for Britain if I was, but I am not.’
The comment drew an angry response from Brexiteers, with Tory MP Nigel Evans saying: ‘I wouldn’t put Juncker in charge of my wine rack.’
Environment Secretary Michael Gove – one of 11 Cabinet ministers at the Chequers meeting – said that divergence from EU regulations would allow Britain to impose ‘even higher standards’ in areas like environmental protection.
He rejected suggestions there was a ‘tension’ between his environmental agenda and the UK’s bid to secure freedom to set its own regulations, insisting the Government was seeking ‘a green Brexit’.

‘One of the things about Britain leaving the European Union is that it gives us the opportunity to look at all of these areas and see how we can meet even higher standards,’ Mr Gove told reporters.
But Mr Gove was mocked by the deputy head of the European Commission Frans Timmermans.
Retweeting a report that Mr Gove might ban plastic straws, Mr Timmermans wrote: ‘@michaelgove One step ahead of you. EU legislation on single-use plastics coming before the summer. Maybe you can align with us? #EUDoesntSuck.’
Earlier, Health Secretary Jeremy Hunt said Britain would not be accepting Brussels dictats on regulations.
‘There will be areas and sectors of industry where we agree to align our regulations with European regulations: the automotive industry is perhaps an obvious example because of supply chains that are integrated,’ he told BBC Radio 4’s Today programme.
‘But it will be on a voluntary basis, we will as a sovereign power have the right to choose to diverge and what we won’t be doing is accepting changes in rules because the EU unilaterally chooses to make those changes.’
As Remainers marshal their forces for a push to water down Brexit, Jeremy Corbyn is expected to confirm a shift in policy on Monday to support staying in a customs union with the EU.
Ms Soubry’s amendment has already been signed by half a dozen Tory MPs – including former ministers Nicky Morgan and Stephen Hammond.
Ex-attorney general Dominic Grieve today indicated he would back the change.
Even if the amendment is passed, it could not legally bind the hands of ministers in the talks.
However, it could be politically devastating and undermine Mrs May’s credibility to conduct the negotiations. There are concerns that defeat could bring down the government.
The discussions at Chequers involved the 11 most senior Cabinet members.
Before the meeting there were thought to still be significant differences between Brexiteer and Remainer factions on how far Britain should diverge from EU rules after we leave the bloc.
A series of previous meetings of the inner circle of ministers had failed to come to firm conclusions.

Mrs May appeared to have enlisted some help to try and get a better outcome – with a border collie sheepdog seen being driven on to the estate in a Landrover.
Remainers such as Philip Hammond and Amber Rudd reportedly argued for a softer approach, while Boris Johnson and Michael Gove favoured a cleaner break.
The other ministers who attended were David Davis, David Lidington, Liam Fox, Karen Bradley, Gavin Williamson and Greg Clark, and chief whip Julian Smith.
The group was carefully balanced between pro-EU and Eurosceptics, with Mrs May theoretically holding the balance between the sides.
The PM’s top Brexit civil servant Olly Robbins gave presentations on parts of the negotiations.
The talks also saw interventions from UK ambassadors to European capitals, including the top diplomat in Paris Ed Llewellyn – David Cameron’s former chief of staff.
The Chequers summit was part of a ‘road to Brexit’ series of events intended to set out the Government’s ambitions for a post-withdrawal settlement with the EU.
The gathering of the Brexit war Cabinet was held at the PM’s Chequers country retreat, and lasted until 10pm
