There was a feature on this story on Newsnight last night. The Government are taking straps to outlaw so called SNAPSS lawsuits whereby the rich and powerful can hit individual investigators with expensive and time consuming litigation which protects them from further investigation. It seems to me that this is an admission that the story in Open Democracy is true, but the line appears to me that this is procedural and the mistake was down to civil servants - interestingly, the Tory head of the Foreign Affairs Committee I think it was, said in an interview that the Government proposals did not go far enough.
