In one email headed "Jimmy Savile - paedophile", BBC producer Meirion Jones, who was involved in establishing the axed Newsnight report, flagged up the idea of an investigation just hours after the presenter's death was announced.
He proposed the suggestion, possibly for Panorama, because he said some of the girls who had been molested by Savile were ready to talk about their experiences.
He wrote: "Some of the girls are now prepared to talk about this which might make a core to a film about what Jimmy Savile really got up to - and of course he's dead so he can't sue."
His emails also contain vivid transcripts of the sexual activities in which girls at Duncroft approved school - where Savile was a regular visitor - were encouraged to take part.
