Theresa May told she’ll ‘break the Tories’ if she does a Brexit deal with Jeremy Corbyn

THERESA May was told she could “break the Conservatives” if she does a Brexit deal with Jeremy Corbyn.

Iain Duncan Smith made the warning as he urged the PM to hurry up and quit next month.

As ministers prepare to hold more talks with Labour, the ex-Tory leader said the party will “revolt” if she accepts an EU customs union.

He also said it would be a “disaster” for the party to fight Euro elections and Britain must leave “deal or no deal” before the vote at the end of May.

The PM’s deputy David Lidington yesterday repeatedly refused to rule out keeping Britain in a form of customs union with Brussels as the price for Labour’s support.

But Mr Duncan Smith told The Sun: “If they do that the Conservative party will revolt.

“That will break the Conservative party. It will be a bridge too far.”

But a Labour source played down talk that a deal could be struck this week.

The warning came as:

• Polling analysis revealed the Tories are on course to lose 59 seats and hand the keys to No10 to Jeremy Corbyn if a snap election was called
• Dozens of local Tory chairmen wrote to the PM saying they will refuse to campaign for the Tories in the European Parliament elections
• Two ex-chairmen of the powerful Tory backbench 1922 Committee said the rules could be torn up to oust Mrs May quicker
• Tory grandee Ken Clarke warned he could quit the party if a hardline Brexiteer is elected leader

While MPs are away for Easter this week, the Brexit civil war shows no sign of easing.

Mr Duncan Smith said the Tories must tear up plans to delay Brexit until Halloween to avoid a bloodbath at the EU election polls.

He told the BBC’s Andrew Marr show: “I really urge the Prime Minister to be very clear that we are not fighting the European elections.

“Any idea of doing that is a disaster.”

Calling for her to quit, he added: “She said she would go as and when the agreement was ratified which was looking at around about May, June. I think those dates still stand.”

It came after a “poll of polls” revealed the Tories would lose dozens of seats if another general election is called - with Amber Rudd and Mr Duncan Smith both expecetd to lose.

And in another hammer blow to Mrs May, former 1922 Committee chairmen Michael Spicer and Archie Hamilton said party rules that mean she cannot be ousted by her own MPs until December, can be torn up.

Under the current system, the PM was given 12 month immunity after winning a confidence vote last December.

But the two Tory grandees wrote in the Sunday Telegraph that MPs are “quite within their rights” to change the rules.

Meanwhile, Mr Clarke - an arch-Remainer and the Tory Party’s longest-serving MP - told students at Nottingham University he could quit the Tories.

The former Chancellor said he would “probably” join the breakaway group of pro EU MPs known as Change UK if the Cabinet became dominated by hardine Brexiteers.
