THE SNP is rotten at the core and “poisoning Scotland’s democratic institutions”, Labour has claimed, in a fiery First Minister’s Questions dominated by the Alex Salmond affair. Rejecting the charge, an angry Nicola Sturgeon accused interim Labour leader Jackie Baillie of being Mr Salmond s chief spokesperson by spreading such misinformation. The First Minister was also forced to deny there had been a “cover-up” of Mr Salmond’s evidence to an inquiry, after a department led by one of her cabinet members had it censored. The sections deleted by the parliament after advice from the Crown Office related directly to whether Ms Sturgeon had lied to MSPs.
