Remainer MPs are plotting a last minute ambush to force Theresa May to rule out a damaging no deal and to delay Brexit Day.
A cross-party group has been holding secret talks to draw up a fresh version of an amendment tabled by Labour MP Yvette Cooper to extend article 50.
The move, expected to be announced this evening, comes after the Prime Minister asked the Commons for another fortnight’s grace to continue talks with the EU.
Mrs May said she needed more time but confirmed they would get another chance to have their say in votes on Brexit on February 27.
But the Remainer MPs want to put her on notice that she will not be able to delay her Brexit “high noon” beyond that point.
The Mirror has learned that Ms Cooper plans to table a Brexit amendment along with Tory grandee Sir Oliver Letwin today or tomorrow.
But the pair are NOT expected to put their proposal to a vote until the end of the month – their best chance of getting it through Parliament.
One source told the Mirror: “In terms of maximising Tory support for the plan, it’s clear they want to give her one final opportunity to get her deal.
“So it’s likely that it will be put to a vote at the end of the month, rather than now. At that stage, there are likely to be Tory resignations over it.”
Ms Cooper and Mr Letwin’s plan would remove the time limit for delaying Brexit Day from an earlier version of the amendment, which was defeated by MPs in January.
Instead it would make the PM decide the length of the extension she would be forced to request from Brussels. Read more
