REBEL Tory MPs will be helping Lords stop Brexit if they vote against her in a Commons showdown this week, Theresa May has warned.
The PM also lashed out at peers for going way beyond their constitutional role to try and overturn the landmark referendum decision.
At least 15 pro-EU Conservative backbenchers have warned No10 they may side with Labour in crucial votes on Tuesday and Wednesday.
They are looking at supporting four of 15 different amendments enforced on the EU Withdrawal Bill by the upper house, dubbed by Brexiteers as 'wrecking moves'.
Laying down the gauntlet to them, Mrs May said last night: “Of course, the Lords has a revising role to play - but some of the amendments that were passed and the comments that were made went far beyond that.
“You had Peers talking about stopping Brexit or trying to tie the Government’s hands in the negotiations.
“This Government is delivering on the decision made by the country in the referendum to leave the EU and we will not accept anything that prevents us from taking back control of our money, laws and borders”.
Mrs May added: “Let’s remember what the Withdrawal Bill is for: it’s about delivering a statute book that is ready for Brexit day”.
The four key amendments are on forcing the government to go back to Brussels with changes after a final vote, the Good Friday agreement, staying in a customs union and joining the EEA.
Tory whips are frantically trying to broker deals with their rebel MPs this weekend to avoid defeat on any of the four, which could cripple Mrs May’s negotiating hand.
No10 sources last night said they were hopeful.
But an even bigger test comes next month, when Tory rebels will also try to enforce a post-Brexit customs union with the EU as well as EEA membership.
It has emerged that Mrs May told Cabinet ministers last week that the EU will not take any of her negotiating demands seriously until she can prove the Commons will not enforce any serious changes to them.
The PM will also confront Tory rebels in person on Monday night at a 1922 Committee meeting of all 316 Tory MPs.
