ITV has said it stands by a documentary which claims Sir Jimmy Savile sexually abused schoolgirls after a member of his family said they are "disgusted and disappointed" by the allegations.
Exposure: The Other Side Of Jimmy Savile, which airs later this week, details claims from women dating to the 1970s, including allegations that he abused girls in his Rolls-Royce and at BBC TV Centre.
Roger Foster, Sir Jimmy's nephew, said his family is "disgusted and disappointed" that the allegations are being made when the presenter, who died on October 29 last year aged 84, is no longer around to defend himself.
An ITV spokesman said: "This documentary is the result of an in-depth investigation into long-standing allegations of serious and widespread sexual misconduct by Sir Jimmy Savile. Because of the very serious nature of the claims made by several interviewees in relation to this, particular care and consideration was of course given to the decision to produce and broadcast this programme.
"The programme takes full account of the fact that Sir Jimmy is not here to defend himself against these claims."
Mr Foster, from Goole, East Yorkshire, said he is not only concerned for Sir Jimmy's reputation and legacy but also for the damage the allegations could do to his charities.
"I just get so disgusted and disappointed by it. The guy hasn't been dead for a year yet and they're bringing these stories out. It could affect his legacy, his charity work, everything. I'm very sad and disgusted," he said.
"I just don't understand the motives behind this. I just think it's very, very sad you can say these things after someone's died and the law says you can't defend yourself when you're dead."
Sir Jimmy was famous for TV shows like Jim'll Fix It and Top Of The Pops as well as being a DJ on BBC Radio 1.
The BBC responded to reports that inappropriate behaviour by Sir Jimmy was an "open secret" at the corporation by saying it found no evidence of any misconduct by the broadcaster.
