RUTH Davidson has tried to reboot her campaign unveiling a “five-point” election pledge — four of which relate to opposing independence and a second referendum.

As the campaign enters its final week, polls suggest the Scottish Conservatives may be losing support as a consequence of a disastrous contest south of the Border plagued by pledges made in the party’s UK manifesto which would hit older voters and the failure of Theresa May to turn up for televised leaders’ debates.

In April, the Tories were on course to take 33 per cent of the vote north of the Border — picking up as many as 12 seats, but on Wednesday the latest opinion survey from Ipsos Mori for STV suggested in just a few weeks support had slumped to 25 per cent with seat predictors forecasting they would get a total of seven seats.

Yesterday, Davidson ramped up her anti-independence case issuing a five point pledge which would be made by any Scottish Conservative MP elected north of the Border.

The five point pledge set out in a statement were: “respecting Scotland’s decision to stay in the UK; opposing a second referendum; delivering for Scotland — so we lead the UK, not leave it; strengthening bonds between Westminster and Holyrood and working for the best Brexit deal in Scotland and the UK.”

Launching the pledge in South Queensferry, Davidson said: “We want to send a strong team of Scottish Conservative MPs to Westminster not to divide but to deliver for Scotland. Every Scottish Conservative MP will stand by our decision to say no to independence.”

Responding to Davidson, a SNP spokesman said: “The Tories’ independence obsession is a smokescreen for their damaging policies. This election is a clear choice between the SNP, who will stand up for Scotland and our communities, and the Tories, who want to silence Scotland.”

Out on the campaign trail in Edinburgh, Nicola Sturgeon said voters in Scotland could play a decisive role in the election result as the UK polls narrow.

An opinion poll yesterday indicates the Conservatives’ lead over Labour has been reduced to just three points.

While the SNP leader said the Prime Minister is on course to win on June 8, she suggested the size of the Tory majority could come down to the outcome in Scotland.

A new UK-wide YouGov poll for The Times puts the Tories on 42 per cent down one point since the end of last week, with Labour up three on 39 per cent and the Liberal Democrats down two on 7 per cent level with Ukip.

Last night the SNP announced Sturgeon will visit 30 constituencies across Scotland as the party ramps up its campaign.

“The Tories have been completely exposed in this election campaign, with a weak and evasive Prime Minister who is unable to answer basic questions on the impact her policies will have on people across the country — from the dementia tax, to the removal of the winter fuel allowance, cuts to public services and social security and the consequences for jobs of an extreme Brexit, the Tories have been found completely wanting,” said the SNP leader.

“What is clear is that it will be ordinary people who pay the price of their plans.

“As the polls narrow across the rest of the UK, whether or not the Tories can increase their majority could come down to the outcome in Scotland.

“So while they may still be on track to win the election in the rest of the UK, Scotland now has the opportunity to hold the Tories firmly in check.”

Labour leader Kezia Dugdale and Lib Dem leader Willie Rennie were also campaigning in the Capital.

Rennie began his “flying finish” with a visit in Edinburgh West, one of the party’s top targets, while Dugdale was in Edinburgh East.

The Lib Dem leader said: “I am set to visit target seats right across Scotland where it is a straight choice between Liberal Democrats and the SNP. My message to voters in these areas is give us your vote and help us beat the SNP.

“These seats are the difference in changing the direction of this country. A vote for a Liberal Democrat is a vote against another divisive independence referendum, it’s a vote for a chance to reject a bad deal on Brexit and it’s a vote on prioritising investment in our services like mental health.”

Meanwhile, it was reported last night by STV Unionist parties are working together by fielding “paper candidates” in some key SNP constituencies they are looking to win.

It was claimed the move is aimed at ensuring an anti-SNP vote is not split in marginal seats, such as Edinburgh South, Edinburgh West and East Lothian. Labour, the Conservatives and the Liberal Democrats are fielding contenders in all 59 seats but some will be “paper candidates” — they will appear on the ballot paper but will not be actively campaigning.
