Theresa May will unveil her Brexit 'Plan B' today - trying to win over Tory Eurosceptics and the DUP by securing more concessions from the EU.
The PM has been scrambling to find a way through after her deal was humiliatingly crushed in the Commons last week.
But in a conference call with Cabinet last night Mrs May effectively ruled out trying to find a cross-party consensus - instead making clear she will focus her efforts on bringing Brexiteer rebels and the DUP back onside.
The approach has been branded 'one more heave' by ministers, but it is far from clear that the EU is willing to give enough ground on the crucial Irish border backstop issue.
Mrs May will appear in the House later to explain how she intends to proceed.
She will also table a 'neutral' motion to be debated and voted on - along with any amendments tabled by MPs - on January 29.
Government sources said she would be holding further talks with MPs, as well as business leaders and trade unionists, throughout the week.
But Labour leader Jeremy Corbyn has refused to hold discussions with the PM, and there has been little success for the government in trying to peel off Opposition MPs. The deal was hammered by a record margin of 230 votes in the Commons last week.
