And the article at IT-Networks has a further note on Sir King’s statement:

That sequence of events led Sir David King, the government’s former chief scientist, to say that it must have been “carried out by a team of skilled professionals, either on behalf of a foreign government or at the behest of anti-climate change lobbyists in the United States”. But he quickly backed away from that statement, admitting he had no inside information.

So I do not agree that this article is biased. They reported the facts accurately.
