David Cameron's spin doctor Craig Oliver has been caught on camera attacking BBC correspondent Norman Smith over the broadcaster's coverage of the Jeremy Hunt scandal.
In the video posted online, Oliver criticises Smith's report linking David Cameron to the controversy surrounding culture secretary Jeremy Hunt over his relationship with News International as the reporter stands outside Number 10 Downing St.
The footage, posted by political blogger Guido Fawkes, reveals Oliver to be completely unaware that the BBC's camera is rolling behind him as he bickers with Smith.
Oliver, who previously worked as a high-profile editor at the Beeb, complains to Smith that mentioning Cameron in the same sentence as Hunt and the Murdochs reflected Smith's own opinion rather than objectively reporting the facts of the scandal.
He goes on to aggressively defend Jeremy Hunt's involvement in the BSkyB bid, saying Hunt only made an "infinitesimal manoeuvre" in asking the prime minister not to turn down the Murdochs' bid, adding that Hunt would be "rightly, deeply upset" that Smith's report suggested that Cameron was in any way involved in shady dealings during the bid.
Smith seems to easily brush off Oliver's criticisms after he storms away.
Oliver, who edited the BBC's six and 10 o'clock news, replaced Andy Coulson as communications director at Downing Street last year after Coulson was forced to step down over phone hacking allegations during his editorship at the News of the World.
