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. 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. The Home Office's permanent secretary, Mark Sedwill, admitted, however, that a further 114 documents relevant to allegations of child abuse were missing from the department's records. That discovery was made last year by an independent review into information received about organized child sex abuse but was not published in its report. Sedwill [said] the missing documents were some of the 36,000 records which officials presumed were lost, destroyed or missing.
