It's highly unlikely to be the side that has been suppressing evidence is it?
It is becoming apparent that the side suppressing evidence is the SG.
It would also not surprise me, with the size of the split in the SNP, which is getting wider by the day, that the leak came from within the SNP. Sturgeon appears to be running out of road and I have no doubt that there are Salmond supporters that will only be too happy to provide material that will speed up that process.
As an aside:
Did you know that the Legal Advice given to the SG was subjected to a Court Order banning its publication ?
Neither did I, however many cult members believe this to be the case and have stated this repeatedly in the comment sections of The Herald.
That is how delusional some of them are.
