Musket: "A bit of a mental leap to say his nephew knew he abused children so you are sure they all did."

I believe Keith is referring to assertions made by Savile's nephew Guy Marsden, who has accused Savile of using him as an intermediary between adults and younger children at paedophile parties when he was thirteen, had this to say about other members of Savile's family:

"Other members of Savile's family spoke out last week to condemn a TV programme alleging the DJ sexually abused teenage girls, but the nephew said many relatives were aware of his sordid past."
