In the same article, Labour MP Tony Wright, chairman of the public administration select committee - the parliamentary committee which would look into any impropriety- had this to say: "I am not sure which authorities Gordon thought he was talking about - the only one I can think of is the Conservative Party" and "we are not talking about corruption here, there was no corruption. We're not talking about law-breaking, there is no law-breaking."
Meanwhile, the Electoral Commission has said: "There is no offense in electoral law in soliciting a donation... no one has presented any evidence under legislation that an offense has been committed.''
Leaving aside the fact that Osborne has strongly denied a donation was solicited at all, their conclusion also seems pretty clear. So who on earth is Gordon Brown talking about? Maybe this lot?
