Former Cabinet minister Leon Brittan has been named in top secret files uncovered following a review into historical child sex abuse in Westminster.
Peter Morrison, who was an aide to Margaret Thatcher, ex-diplomat Sir Peter Hayman and former minister William van Straubenzee are also mentioned in the documents released by the Home Office.
One of the files relating to Hayman was held by the Cabinet Office but “overlooked” during a previous trawl for information.
Documents that refer to Straubenzee had been earmarked for destruction but National Archives officials flagged them up to the Government.
A group of papers that name Morrison, Brittan, Hayman and Straubenzee were “found in a separate Cabinet Office store of assorted and unstructured papers”.
They also contain references to the Kincora children’s home in Belfast where boys were abused,
The Home Office said a fresh search of the archives had been carried out after a file emerged earlier this year that should have been submitted to the Wanless and Whittam inquiry into the handling of allegations that prominent figures were child abusers.
