A report into Jimmy Savile and the culture and practices at the BBC in the wake of revelations of a long campaign of sexual abuse by the late star while he worked there is due to be published today.
The findings of Dame Janet Smith's review, which are finally being released more than three-years after an inquiry was launched, will take into account information gathered from interviewing some 375 witnesses in connection with Savile.
More than 100 people were also interviewed about fellow shamed presenter Stuart Hall during the inquiry.
- Why was Savile being investigated as part of the review?
Former Top Of The Pops presenter Savile was named as one of the country's most prolific sex offenders after hundreds of people came forward to say they were abused by him whilst he worked at the BBC.
He became the subject of Operation Yewtree, a formal criminal investigation by the Metropolitan Police, a year after his death in 2011 which prompted the launch of a review into his conduct in 2012.
- Who else has been looked at as part of the review?
Stuart Hall's name was added to the inquiry in 2013 after he was jailed for admitting indecently assaulting 13 girls - one as young as nine - between 1967 and 1985.
- What can we expect from the review?
A leaked draft version of the report suggested that the BBC will be condemned for its "deferential culture" and "untouchable stars" during the time that its presenters were committing their acts of sexual abuse.
However, Dame Janet has already expressed disappointment at last month's leak and said the draft version was out of date.
