This is very interesting - \link{http://www.telegraph.co.uk/news/uknews/crime/jimmy-savile/9623109/Jimmy-Savile-Secret-of-BBCs-first-sex-scandal.html\a Telegraph report from 2012} about Savile
There was a police inquiry in 1971 relating to the diary:
'Top of the Pops... was the subject of a separate but related police inquiry in 1971, led by the same detectives, into claims that a 15-year-old dancer on the programme had been “used” by disc jockeys and other celebrities.
The girl, Clair McAlpine, subsequently committed suicide. She had named Savile in her diary as one of those abusers, according to her family'
Then there was a separate payola inquiry, which was the Brian Neill QC one:
"The payola scandal was just what Savile would not have needed. The BBC inquiry was led by Brian Neill, a brilliant young QC, with interviews conducted by James Crocker an outside solicitor.
The Neill report has never been made public, and it is not known whether Savile was named in its final written version, but a source said: “Savile was one of a number of DJs asked about the payola scandal. Savile came before Crocker but just made fun of him."
My italics.
So where does Brian Neill supposedly interviewing TB about Clair McAlpine fit into that? (Assuming the DT has reported it accurately. Although it does say the same team of police were involved in both the sex & payola inquiries so maybe Brian Neill led both.)
Have the BBC still got the Neill report? Does it mention TB?
