A former teacher from Liverton has revealed he was paid to garner information about parliamentary paedophiles.

Barrie Trower was working in the education wing at Wormwood Scrubs prison when he was ordered to provide verbal evidence about inmates and their links with senior politicians, the Metropolitan Police, and high-ranking civil servants.

He provided 'sexually graphic' facts from unsuspecting inmates between l967 and l978 – material which helped make up the infamous missing dossier on Whitehall paedophiles.
