SCOTTISH Labour is on course to lose 50% of its vote in Scotland in a snap Westminster election, according to internal party polling.

The figures, which were revealed by The Scotsman, showed that if Jeremy Corbyn did not say whether he would campaign for Remain in a second EU referendum, the party risks losing the faith of 49.2% of those who backed Labour in 2017.

At Labour's conference in Brighton today, Corbyn's position of remaining neutral on Brexit was officially backed.

The polling was carried out by trade unions ahead of that vote being held. The SNP and LibDems could wipe Labour out in the Commons if it proves accurate – the party currently have seven Scottish MPs.

The research found that the SNP would be the biggest beneficaries of Labour failing to declare its support for Remain, with a fifth of those who voted for the party in 2017 moving to the SNP.

The LibDems would take 15% of Labour voters, the Brexit Party 6% and the Conservatives 3%.

Scottish Labour leader Richard Leonard has called for the UK party to back Remain – but Corbyn has not shifted his position.

Corbyn has promised that a government he leads will negotiate a new Brexit deal and put it to a referendum but has resisted calls to say how the party should campaign in that public vote.

Delegates at the conference in Brighton who backed the statement setting out his position broke out into a chorus of "oh, Jeremy Corbyn" after the result of the vote was announced.

In chaotic scenes, the conference then rejected a motion which would have called on Labour to come out in support of Remain now rather than waiting until after an election.

The result is a boost for Corbyn, who has argued that Labour should go into the expected general election without making a decision on how it should campaign on the referendum his party has promised within six months of taking office.

A decision on how the party would campaign in the referendum would be taken at a subsequent special conference.

The vote came after shadow cabinet ministers Emily Thornberry and Sir Keir Starmer both used their keynote conference speeches to say they would back Remain.
