SNP challenged to prove MSP's claim that border would 'create jobs' THE SNP MSP who sparked a furore by claiming that a post-independence trade border with England would “create jobs” has been challenged to prove it. As Nicola Sturgeon today tried to defuse the growing row, Scottish Tory leader Douglas Ross said Emma Harper should back up her controversial claim. He said: “The SNP have to substantiate those claims from one of their current MSPs and a candidate in this election.” Ms Harper, who is the SNP candidate in Tory-held Gallloway & West Dumfries, was accused of spouting “half-witted nonsense” after an interview with ITV Border yesterday.
