He said: “There has also been no credible strategy to deliver a referendum. “The SNP ‘feeble fifty’ jibe when Labour’s 50 Scottish MPs (69%) failed to deliver devolution after the 1987 general election has come home to roost. “With 48 (81%) of Scotland’s 59 MPs, the SNP is unable to deliver a referendum.” He added: “Intoxicated spin of evidence from opinion polls has not helped. “Support has grown but far from the consistent and convincing lead that would be necessary to risk another referendum. “We hear less these days about the 60% that many members predicted lay just over the horizon.” He suggested it was ironic that SNP Constitution Secretary Mike Russell recently quoted Canon Kenyon Wright of the 1990s Scottish Constitutional Convention saying that if the UK Government said No to a referendum “We say Yes and we are the people”.
