A snap election now could see Jeremy Corbyn in power propped up by Nicola Sturgeon's SNP, according to new analysis.

A poll of polls by the Electoral Calculus website found on current standings the Tories would still end up as the biggest party with 286 MPs.

However, they would be well short of a majority in a 650-strong parliament, even with support from the DUP.

By contrast Labour securing 283 seats could potentially form a government if the SNP's 43 MPs agreed to prop them up.

The figures give a snapshot of the situation - but the outcome is likely to be much worse for the Tories if they are forced into a panicky election by Brexit chaos.

The SNP would also be highly unlikely to enter a formal coalition with Labour having witnessed the damage the Lib Dems sustained from their alliance with the Conservatives.

The two parties have long been in bitter competition in Scotland.

The chances of an election have been rising as Mrs May battles to get her Brexit deal through Parliament in the face of bitter opposition from rebel Tories, Labour and the Lib Dems.

The scale of criticism makes defeat look almost inevitable in a crunch Commons showdown on December 11.

Shadow Brexit secretary Sir Keir Starmer confirmed today that Labour will call a no-confidence vote if Mrs May loses - the first step towards forcing an election.

But Sir Keir also hinted that his favoured outcome is a second referendum - suggesting staying in the EU should be an option in the ballot, and no-deal Brexit should not be.

Electoral Calculus looked at recent surveys that covered 13,000 voters.

Chief executive Martin Baxter told the Sunday Telegraph that the outcome it predicts would not do much to end the deadlock over Brexit.

"Parliament would be badly hung and would not be able to do very much with those figures," he said.

Tory MPs whose seats would be at risk include Remainer World and Pensions Secretary Amber Rudd in Hastings & Rye, and Brexiteer Zac Goldsmith in Richmond Park.

Even if mooted new constituency boundaries are taken into account the Tories would still be 22 short of an overall majority.
