If my recollection is right, it was Guido Fawkes who first broke the story on Peter Hain's campaign funding on the afternoon of 3 December HERE. It was this story which provoked Peter Hain to contact the Electoral Commission. If Guido hadn't run it, would Hain have come forward? I doubt it very much.
But those of you who have longer memories may remember THIS post by Guido back in May. This revealed Hain's campaign budget and posed the question: how much is Peter Hain's campaign costing? It was that blogpost which ruined Hain's chances in the deputy leadership election. The huge figures went down very badly among Labour Party members, and particularly the trade unions.
Bloggers do not exist to get political scalps. But when a blogger reveals possible law breaking and drives the media debate, as Guido has done, let's recognise that as a good thing and give him the credit he is due.
