Yesterday saw the Jimmy Savile sexual abuse scandal throw up even more lurid accusations, as former colleague, Paul Gambaccini, speaking on BBC Radio 5 live, accused Savile of being a necrophiliac, whose usual sexual partners were "underaged subnormals" - in reference to the fact that Savile targeted vulnerable and impressionable children in hospitals, institutions and on his TV shows.

And from colleague revelations, it was the turn of George Entwistle to fire fight on behalf of the BBC over a pulled Newsnight investigation exposing Savile's conduct, which he admitted to the Commons Committee "should never have been dropped." But questions have also been raised about Mark Thompson, the previous BBC Director General, and what he knew about the Savile abuse allegations while at the BBC.

The BBC have also acknowledged other allegations abuse, which has come to light, prompting the release of a statement, saying: "As a result of the allegations about Jimmy Savile and subsequent contact from staff, former staff and members of the public, we are currently aware of nine allegations of sexual harassment, assault or inappropriate conduct regarding current staff or contributors. Some of these cases have been passed to the police where appropriate."

As the Savile investigation has now gone to the highest level of the BBC, the BBC Trust chairman, Lord Patten, has released a a statement saying the BBC's inquiries would be comprehensive and fully independent.
