SUPPORT for Scottish independence would soar if Theresa May wins today’s General Election, a new poll has revealed.

A survey published yesterday found 31 per cent of voters said they would be more in favour of self-determination if May leads a re-elected Conservative Government.

The figure includes 15 per cent of voters who wanted Scotland to stay in the UK in 2014 — which added to the 43 to 45 per cent of voters who currently back Yes would give the First Minister sufficient support to win a new referendum.

The YouGov poll for The Times also found Labour voters were the most likely to switch from No to Yes in a new referendum if faced with the prospect of a Conservative Government for five more years.

In contrast, the survey revealed if Labour wins only 12 per cent of Scots voters said they would be more likely to back independence.

The development came as David Mundell yesterday ruled out second independence referendum until 2022 if the Conservatives win the election.

The Scottish Secretary said he did “not see circumstances in which we would be having a referendum in the next five years”.

Nicola Sturgeon says there should be such a ballot when the terms of the UK’s exit deal from the European Union (EU) are clear and has previously suggested a vote could be held between autumn 2018 and spring 2019.

She argues this option is necessary to give Scots, who voted to remain in the EU, an alternative to the “extreme Brexit” proposed by May and the Conservatives.

But May told the Scottish Daily Mail yesterday: “I have been very clear now is not the time to be talking about a second independence referendum.

“That is because now — with the crucial Brexit negotiation starting 11 days after the poll on Thursday — we need to ensure we’re working together, not pulling apart.

“I would say to people in Scotland that if they support the Union, if they believe in the Union as I do, then they should be voting Conservative on Thursday.”

The Tory leader said it was time “Nicola Sturgeon stopped having this tunnel vision about independence”, adding: “My message to Nicola Sturgeon and the Scottish nationalists won’t change on this — that now is not the time to be talking about an independence referendum.”

Mundell — who was the only Tory MP returned from Scotland in 2015 — said: “If there is a Conservative Government, I don’t see circumstances in which we would be having a referendum in the next five years because we are committed to not having a referendum until the Brexit process has played out.

“I think it will take the five years of this Parliament to play out the Brexit process.

“The contrast with (Jeremy) Corbyn is he’ll still do a deal with them and that is the message for anybody thinking of voting Labour — Corbyn would do a deal with the SNP.”

Labour leader Jeremy Corbyn, campaigning in Glasgow yesterday, said he did “not see the urgency or the need for an independence referendum” though has previously said he “would open discussions” about it with the First Minister should he become Prime Minister.

The Times poll also found that some 48 per cent of voters in Scotland support the SNP’s proposals for Scotland to have a seat at the Brexit negotiating table.

Commenting, SNP Depute Leader Angus Robertson said: “There is clear backing for our fair proposals for Scotland to have a seat at the Brexit negotiating table – it is simply untenable for the Tories to continue to block Scotland having a say on these vital negotiations.

“This is of course something that Ruth Davidson agreed with after the EU referendum — before she got in line behind Theresa May’s extreme Brexit plans and sold out Scotland.

“The divisive and arrogant Tories cannot keep trying to prevent Scotland from having its say on Brexit – and voters across Scotland agree.”

Some 1093 people were surveyed between June 1 and June 5.
