This is not opinion. It’s been investigated by the police and it is fact.
The only reason it didn’t come out before he died was because she protected him.
The crimes surrounding Jimmy Saville continues in that Scotland Yard, his employer, the BBC, and British politicians/royalty all admitted that there were numerous reports of his activities after he died, but there has been no follow-up investigation or charges brought against the numerous people that participated with him and covered his actions up. No one has been called to account for their failures to investigate and/or report his crimes. Very likely because many of them were part of his cohort.
