A dossier compiled by an MP detailing allegations of a 1980s Westminster paedophile ring is one of more than 100 potentially relevant Home Office files destroyed, lost or missing, it has emerged. The government faced fresh calls for an overarching inquiry into historical cases of paedophilia as it was revealed that a total of 114 Home Office files relevant to allegations of a child abuse network have disappeared from government records. David Cameron has already ordered the Home Office permanent secretary to look into what happened to a lost dossier given earlier in the 1980s to Leon Brittan, then home secretary, by the campaigning Tory MP Geoffrey Dickens. The revelation that further relevant documents have disappeared will raise fresh fears of an establishment cover-up. Dickens, who died in 1995, had told his family that the information he handed to the home secretary in 1983 and 1984 would "blow the lid off" the lives of powerful and famous child abusers, including eight well-known figures. In a letter to Dickens at the time, Brittan suggested his information would be passed to the police, but Scotland Yard says it has no record of any investigation into the allegations. On Saturday the Home Office made public a letter to Keith Vaz, chairman of the home affairs select committee, in which the department confirmed that correspondence from Dickens had not been retained and it had found "no record of specific allegations by Mr Dickens of child sex abuse by prominent public figures".
