The BBC has been criticised for the culture within which Jimmy Savile's paedophile activities took place, according to a news agency that has been leaked a version of Dame Janet Smith's report.
The Exaro news agency said it has seen a copy of the review that accuses the the broadcaster of having a "deferential culture", "untouchable stars" and "above the law" managers.
The retired judge does not criticise the BBC for not uncovering the abuse, it is claimed.
The review reportedly said it was "disappointed" the report had been leaked, adding the agency had seen an early draft.
In a statement the review told BBC News: "That document is out of date and significant changes have been made to its contents and conclusions.
"The document should not have been made public and cannot be relied upon in any circumstances.
"The review will work with the BBC to arrange publication of its final report as quickly as possible to ensure that accurate and responsible reporting can take place."
The BBC reportedly said it had not seen a copy of the report launched in 2012 in the wake of revelations of a long campaign of sexual abuse by the late star.
According to Exaro "many" BBC employees told the review they had heard about Savile's abuse but feared reporting the allegations to managers.
However, Dame Janet reportedly accepted the claims of senior figures that they were not aware of Savile's sexual misconduct.
An extract of the report published by Exaro said she had heard of incidents that took place in "virtually every one of the BBC premises" where Savile worked.
The DJ was said to have indulged in "sexual touching" while filming for some of the broadcaster's flagship programmes, including Top of the Pops and Jim'll Fix It.
The locations included the BBC Television Theatre, while on set for Jim'll Fix It, Television Centre in connection with Top of the Pops and Broadcasting House, where he worked for Radio 1.
Incidents also took place at the Lime Grove studios and BBC properties in Leeds, Manchester and Glasgow.
