BBC Trust chairman Lord Patten has vowed to "find out the truth" as Savilegate gathered momentum over the weekend with the arrest of former pop star Gary Glitter.
Lord Patten said the BBC would not hide behind smokescreens but "must tell the truth and face up to the truth about itself, however terrible."
He apologised "unreservedly" to the abused women who spoke to the BBC's Newsnight before its report was axed.
Two independent inquiries have been set up - one into the Newsnight report, the other into the BBC's culture and practices in the years Savile worked there.
Meanwhile Glitter - real name Paul Gadd - was arrested in central London on suspicion of sexual offences and released today evening.
He has been jailed in Britain and Thailand on child sex offences.
A government guided by common sense would respond to news that publicly owned Royal Mail has increased profits to £403 million by scrapping plans to flog off the service.
