It was claimed that Douglas Muggeridge, the controller of BBC Radio in the early 1970s, was aware of allegations against Savile and had asked for a report on them in 1973. The BBC stated that no evidence of any allegations of misconduct or of actual misconduct by Savile had been found in its files and later denied that there had been a cover-up of Savile's activities. However, there were claims by some, including DJ Liz Kershaw, who joined BBC Radio 1 in 1987, that the culture in the BBC tolerated sexual harassment.
