The BBC is on a collision course with the Government after rejecting allegations of bias from Downing Street over its coverage of the Iraq war.
In a letter to the prime minister's communications director Alastair Campbell, BBC director of news Richard Sambrook has rejected accusations from Number 10 that the BBC unfairly accused the Government of "sexing up" the case for war, and insisted that the media giant's reporting of the Iraq war had been entirely impartial.
PM Tony Blair however is relying on a Commons enquiry report today to partly vindicate Downing Street's claims, and over the weekend said that the reaction from the BBC was "as serious an attack on my integrity as there could possibly be."
Last night Downing Street said that it was saddened that the BBC should continue to "defined the indefensible".
