Secret plans for a snap General Election have been accelerated by Conservative HQ after last week’s turmoil.

Key marginal constituencies are being offered free campaign managers by Central Office, and candidate selections are being fast-tracked.

The Mail on Sunday revealed earlier this year that No 10 advisers had discussed the plan to hold a fresh poll in the event of the Commons voting down Theresa May’s deal.

She would go to the country for a ‘Brexit Election’ on the ticket of securing a mandate for a new negotiating platform with the European Union. The party’s canvassing activity in marginals has been ‘ramped up massively’ in recent weeks, sources say.

But Tory MPs’ anxieties about another General Election – less than two years after the disastrous campaign that lost the party its Commons majority – will not have been eased by three new polls released this weekend.

One for Opinium carried out on Wednesday – as Cabinet Ministers argued over the deal in a marathon meeting with Mrs May – put the Conservatives at 36 per cent, with Labour leapfrogging them to reach 39 per cent.

Just a month earlier, Opinium had the Tories on 41 per cent and Labour on 37. Ukip have risen two points to 8 per cent, while the anti-Brexit Liberal Democrats have dropped one point to 7 per cent, in a sign few voters are agitating to overturn the referendum result.

Another poll published last night, carried out by Panelbase, put the Tories and Labour neck-and-neck on 40 per cent each.

A third poll, carried out by ComRes on Wednesday and Thursday, had the Tories dropping three points to 36 per cent, with Labour remaining on 40 per cent.

Nervous Tory MPs will recall that they were enjoying a 20-point lead over Jeremy Corbyn’s Labour party at the start of the ill-fated 2017 Election campaign.
