Jimmy Savile denied being a paedophile in a TV programme in 2000. Today the BBC's boss will be questioned by MPs over why the corporation dropped a recent documentary on allegations surrounding the presenter.
Prime Minister David Cameron has accused the broadcaster of changing its story about why it killed a news segment on the accusations.
The powerful broadcaster tried to stem the damage, saying in a statement that a top editor had stepped down from its BBC Newsnight program after he was found to have given incomplete, inaccurate explanations for the decision to keep an investigation of the late Jimmy Savile from being broadcast in December.
The scandal is one of the worst to rock the BBC, long a key player in British public life and often cited as one of the most trusted sources of accurate, unbiased information.
''The BBC is a public service broadcaster that depends on the public trust, and anything that suggests it hasn't been truthful undermines that trust,'' Conservative Party lawmaker Rob Wilson told The Associated Press.
''That's why this is such an important issue for them.'' Police are investigating accusations against Savile and say there may be more than 200 potential victims of the entertainer, the longtime host of the BBC's Top of the Pops and Jim'll Fix It recognized for his garish track suits and platinum hair.
The BBC's tough statement about editor Peter Rippon deepened the suspicion that there had been a cover-up. It is suspected of pulling the Newsnight segment because of its harsh portrayal of Savile, who was hailed as a popular fixture in children's TV when he died at 84 last year.
Wilson said the BBC has tried to evade responsibility for its long tolerance of Savile. ''They were sidestepping the story, hoping it would go away,'' he said.
''The BBC was saying the cultural issues that led to this were in the past, but when we saw BBC looking at the Jimmy Savile issue and finding out uncomfortable things, they appeared to want to cover it up.''
The BBC's backtracking prompted unusual criticism from the prime minister.
''The nation is appalled, we are all appalled by the allegations of what Jimmy Savile did and they seem to get worse by the day,'' Cameron said, accusing the BBC of changing its story about why it decided not to broadcast the piece.
Tim Burt, a managing partner of the Stockwell Communications crisis management firm, said BBC faces a major blow to its reputation at a time when it is entering delicate negotiations with the government about the terms of its charter.
''So to have a civil war inside on a matter of editorial judgment and the handling of potentially criminal investigations could not have come at worse time,'' he said.
The BBC plans to air its own investigation into its actions on a show Monday night (local time). Rippon is the first BBC figure directly blamed for the broadcaster's failure to properly report on abuse claims.
He is stepping down immediately for the duration of the investigation. The BBC Trust, the corporation's governing body, conceded there had been ''inaccuracies in the BBC's own description of what happened in relation to the Newsnight investigation.''
The BBC says Rippon's explanation of his decision in a blog post earlier was ''inaccurate or incomplete in some respects.''
BBC is publicly funded through its license fees and various commercial enterprises; it enjoys a large degree of independence from government but is subject to legislation passed by Parliament.
In a statement released Monday, the BBC cited three problems with Rippon's initial statements about why the segment was not aired.
The BBC said Rippon's blog indicated that Newsnight staff had no evidence against the BBC when in fact there were allegations that some of the abuse happened on BBC premises.
It also faulted Rippon for saying that all the abuse victims interviewed by the program had told police about the abuse, when in some cases the women had not done so, meaning that police were ''not aware of all the allegations'' against Savile.
In addition, BBC said Rippon had indicated that there was no evidence that anyone working at the Duncroft school was aware of allegations that Savile had abused girls there, when in fact there were indications that ''some of the Duncroft staff knew or may have known about the abuse.''
