BORIS JOHNSON threatened to call an early general election today if MPs did not back plans to accelerate his Brexit deal through Parliament.

Tonight, two key votes are scheduled to determine whether the PM will be allowed to meet his “do-or-die” pledge for Brexit by October 31.

MPs are set to vote on the PM’s Withdrawal Agreement Bill before voting on his accelerated timetable to hurry the legislation through Parliament.

Mr Johnson told the Commons that he would “in no way allow months more” debate over Brexit, as he called on MPs to work “night and day” to scrutinise his plans and avoid a no-deal Brexit in nine days’ time.

Labour leader Jeremy Corbyn said his party would vote against both the PM’s Bill and timetable and accused the PM of “trying to blindside” Parliament with a “disgraceful attempt to dodge accountability, scrutiny and any kind of proper debate.”

Sir Oliver Letwin, a whipless Tory whose namesake amendment has been part of efforts to prevent a no-deal Brexit, said he was “seriously worried” the Bill would be pulled if the timetable was voted down.

He said it would be better to leave with a deal than without.

Rory Stewart, who was among the 21 Tories expelled for voting against no-deal, suggested he could back the Bill but not the programme motion.

Failure to get the motion through could see Mr Johnson forced against his will to accept another lengthy delay to Brexit.

DUP MPs are refusing to back Mr Johnson on the Bill over arrangements for Northern Ireland, but ministers believe they have the support of pro-Leave Labour MPs and ex-Tory independents who would rather leave with a deal.

If the Bill passes under the proposed accelerated timetable, MPs will have the opportunity to put down amendments during the committee stage.

Labour-backed amendments are expected to include attempts to keep Britain closely aligned with the EU through a customs union and to hold a second referendum.

Communist Party of Britain general secretary Robert Griffiths urged MPs to support the Bill so that the issue of Brexit can be “settled,” allowing Labour to go into a general election on “a bold, radical manifesto of domestic policies.”

He said that the alternative would be a campaign in which Mr Johnson accuses Labour of “failing to abide by its own pledge” to respect the referendum vote.
