SCOTTISH Labour is on course to lose all the Westminster seats it gained from the SNP at the last general election, a new poll suggests.

The survey shows plummeting support for Jeremy Corbyn while the Nationalists are set to secure 42 per cent of the Westminster vote.

The SNP will also take back the eight seats it lost to the Scottish Conservatives in June 2017, with the Tories polling at 24 per cent of the vote.

The poll of more than 1,000 Scots by Survation shows Nicola Sturgeon is on course to lead her party to an unprecedented fourth consecutive Holyrood election win.

Published in the Daily Record newspaper, it also suggests another pro-independence majority in Holyrood once the Greens’ seats are included.

Meanwhile, the SNP are set to win 14 more MPs, taking their total to 49 out of Scotland’s 59 seats.

Labour would lose all but one of its seven MPs and the Tories would lose eight. But the LibDems would remain stable, holding on to their four Scottish seats.

Professor Sir John Curtice said the results suggested Labour’s support “is going backwards”, running the risk that they will lose all the seats they regained from the SNP last year.

He said: “Labour’s chances of winning the next UK election rest heavily on making a significant advance north of the Border.”

He said Mr Corbyn’s popularity among voters seems to have slumped, with just 28 per cent of Scots now feeling favourably towards him.

Only 35 per cent of voters had any opinion of Scottish Labour leader Richard Leonard, with just nine per cent viewing him favourably, and 26 per cent unfavourably.

Scottish Tory leader Ruth Davidson is the most popular politician among voters, the polling shows, while Nicola Sturgeon has a favourability rating of -2.

At Holyrood, the survey results would see the SNP dropping four seats while Labour gained two and the Tories lost eight.

The LibDems would enjoy a boost from five to 11 seats, while the Greens would go from six to 10.

SNP deputy leader Keith Brown said it was clear “fewer and fewer people think Labour are a serious alternative”.

But Labour campaigns spokesman Neil Findlay said: “The emerging dividing line in Scotland is between Labour’s plan to invest and build an economy that works for the many, not the few, or further austerity with the SNP and the Tories.”

A Tory spokesman said: “This very much reinforces Labour’s position as political non-entities in Scotland, and proves Ruth Davidson is the only alternative first minister to Nicola Sturgeon.”
