DESPERATE Unionists have launched a bid to keep out the SNP as a new poll predicted gains for the party at next month’s General Election.

Scotland in Union urged voters to “stop the SNP and their Scexit obsession” as it launched a new tactical voting website.

The site from the four-year-old pressure group, which is led by former Labour MP Pamela Nash, covers every Scottish constituency and tells users who enter their postcodes which pro-Union candidate they should back to avoid a local SNP victory and a “divisive” independence push.

An SNP spokesperson said: “It says it all that an organisation fronted by a former Labour MP is advising its supporters to vote Tory.

“Only a vote for the SNP is a vote to escape Brexit, lock Boris Johnson out of Downing Street and put Scotland’s future in Scotland’s hands.”

In Paisley and Renfrewshire North, where Labour came second to the SNP last time, users are advised to vote Conservative – even though they finished in third place.

However, it does advise a Labour vote in Glasgow North East where Jeremy Corbyn’s party aims to defend its 242 majority against the second-placed SNP. And those in the ultra-marginal North East Fife seat, where the SNP’s Stephen Gethins won by just two votes last time, are urged to back the LibDems.

Scotland in Union said it has based the recommendations “on a number of factors, including the result in the 2017 General Election, polling results since then, odds and local information”.

And those who cannot bear to break party allegiances are advised to consider using the Swap My Vote website – which is currently not operational – to arrange a reciprocal voting deal with a stranger living “where your favoured party might have a better chance of winning”.

Responding to the launch, one Twitter user said: “A vote for Labour is as good as a vote for the SNP. These tactical voting sites are useless.”

And another said that “Labour people advocating voting Tory is scummy as hell”.

However, another countered: “I understand your position, I’m in Inverclyde, SNP held by around 380 votes to Labour last time. I’m going to hold my nose and vote Labour.”

A statement on the tactical voting site says it has been created in response to “many requests from supporters for advice on who to vote for to stop the SNP” and includes “fair” suggestions.

It says: “The more seats the nationalists gain in the House of Commons, the louder they will shout about breaking up the UK. Their voice is negative, inward-looking and divisive and they do not speak for the majority of people in Scotland.

“Most voters do not want their ballot paper at this election to be used to divide communities, friends and families with another referendum on Scexit.

“Our voting suggestions do not constitute an endorsement of any candidate or party’s policies.”
