THERESA May has been warned against relying on Labour support to secure her Brexit deal, it has emerged.

Leading Eurosceptic Jacob Rees-Mogg has said it would be “dangerous” to rely on Opposition MPs to win Commons votes.

The PM’s Chequers proposal has been blasted by Brexiteers with Mr Rees-Mogg saying he would vote against it in its present form.

He said: “The most divisive thing for a party is to push through a policy which is opposed by a large number of your supporters on the back of opposition votes.

“I wouldn’t have thought it’s in the interest of the leadership of the party to be so divisive.”

Mr Rees-Mogg, who is chair of the pro-Brexit European Research Group with dozens of Tory MP backers, was speaking to the Financial Times podcast.

Boris Johnson and David Davis both resigned from their Cabinet posts over Mrs May’s plan.

In his resignation speech in the Commons, Mr Johnson called on the PM to rip up her “miserable” blueprint and accused the government of “dithering” over its negotiations.
