The chairman of the BBC Trust, Lord Patten, has said that the BBC will launch an independent inquiry into the allegations against Sir Jimmy Savile.
"These are serious issues," he told ITV News' UK Editor Lucy Manning. "There's no point in having an inquiry which isn't wholly credible."
He also defended the BBC's decision to air tribute programmes despite bosses knowing about a Newsnight investigation into abuse claims. Mr Patten pointed out that many newspapers were printing "hagiographies" of him despite being aware of the "rumours".
Jimmy Savile was questioned as a suspect by police investigating the Yorkshire Ripper, according to a retired police officer.
Jimmy Savile's nephew has spoken of the emotional turmoil his family is going through in the wake of the sex abuse allegations.
A colleague of Jimmy Savile allegedly raped a woman on BBC premises in 1970, ITV News has been told.
