Conservative MPs who vote to block a No Deal next week will be sacked from the party, according to the Sun.
No10 will bar remained rebels from standing at the next general election.
Boris Johnson is planning the move to quell a bid by MPs to rush a law through Parliament to delay Brexit beyond October 31, it has been revealed today.
The PM will treat next week’s vital Commons votes like a no-confidence vote in his Government, with rebel Tories disqualified from contesting their seats.
No10 hopes the move will persuade some waverers not to rebel.
It deals a major blow to Remain MPs hopes of blocking a No Deal as they see next week as the last chance to thwart Mr Johnson’s Brexit plans before he Suspends Parliament the following week.
