What is Nicola Sturgeon hiding?

For as long as it has been rumoured, and even more so since it was confirmed, Nicola Sturgeon’s appearance on Wednesday before the Holyrood committee investigating her government’s unlawful handling of complaints made against Alex Salmond promised to be a challenging, perhaps even chastening, moment for the First Minister.

Twin revelations tonight appear to reinforce that supposition. In spades. If Sturgeon’s administration was not facing crisis before, it undoubtedly is now. At the outset of this process — which followed Salmond’s acquittal on all charges made against him in the criminal trial — Sturgeon promised that she and her government would co-operate fully with the inquiry. Such words are cheap, of course, and require the backing of actions.

Those actions were posted missing. In place of candour, there has been obfuscation. Documents have been withheld and witnesses have demonstrated such inadequate powers of recall it is a wonder any of them rose to hold such senior positions within the civil service and the SNP alike.
