An independent report has found there was chaos and confusion among BBC managers over a shelved report into child sex allegations against Jimmy Savile but no cover-up.
The report said a decision to abandon a current affairs expose of the paedophile behaviour of the late TV presenter was deeply flawed.
The former head of Sky News, Nick Pollard, who carried out the inquiry, has told reporters that managers then mishandled the furore that followed.
"When the full force of the affair broke in October this year the BBC's management system proved completely incapable of dealing with it.
"The level of chaos and confusion was even greater that was apparent at the time.
"Several individuals and departments were making considerable efforts to get to the truth behind the Savile story but leadership and organisation seemed to be in short supply."
The report dismissed claims that the Newsnight probe into the sexual abuse allegations was dropped from the BBC programme to protect tribute shows to the late presenter.
Newsnight's editor and deputy are being replaced after another inquiry criticised a report which led to Lord McAlpine facing false claims of abuse, the BBC reports.
The BBC's head of news is returning to her job, but her deputy Stephen Mitchell is to resign.
