It does not seem inappropriate to me that they withdraw entertainment programmes showing Jimmy Saville, at least on a temporary basis, especially given the gravity of the allegations.It now seems there have been several investigations of his conduct over the years - but all have either been shelved or disregarded, motivated by a desire to "turn a blind eye", or because of concerns over libel allegations, or because of the fears of the impact on the charity work.
Given that some of the allegations relate specifically to the BBC, in the sense that it would seem that several influential employees knew about these events, or that at least some of the events are alleged to have taken place on BBC premises, it would not be suitable to broadcast such shows.
There is a massive difference between airing a documentary, airing information and offering education, and airing an entertainment show...
