"It is an obvious statement that the prime minister would never mislead Parliament, clearly."

The BBC report two incredible claims. First that:

"The prime minister's spokesman would not comment on the leaked document, saying there were "a number of documents that would be around that would have within them assumptions at various stages of the planning process".

He added: "It is an obvious statement that the prime minister would never mislead Parliament, clearly.""

"obvious"? To whom? Not to me that's for sure.

The BBC also report that:

"The Liberal Democrats' Treasury spokesman Vince Cable told the BBC the Conservatives were trying to "make a big political issue out of this".

"I wasn't misled. I think we all realised, who have studied government documents, that cuts were on the way," he said. "

Am I right that Vince Cable and the BBC's line on this is that nobody was mislead because we all knew that cuts were coming so whatever Gordon Brown said in Parliament or at Press Conferences can be ignored because we all knew what was coming? If that is the BBC line then it is fundamentally wrong; if the leaked documents are real then Gordon Brown lied to the House of Commons and at the Press Conference in his reply to Fraser Nelson's straightforward question.

If a Conservative Prime Minister or indeed any senior Conservative politician, had been caught out in a similar way the BBC would be in full outrage mode: Michael Crick would be doing special reports for Newsnight, Jeremy Paxman would be in full sneer mode and John Humphrys would be exuding indignation from every pore. However as it is Gordon Brown, the story came, was under-reported, and is now fading away and being treated as "Conservative claims" and a non-story.

This story has really shone a spotlight on the BBC's pro-Labour bias and even David Cameron must realise the uphill battle he faces to overcome the BBC's blatant bias in the run up to the election and the anti-Conservative vitriol that will be spewed at him and his party should they have the temerity to win the upcoming general election.
