Government papers about the former home secretary Leon Brittan are among a fresh batch of documents which have come to light months after the conclusion of an official review into whether allegations of child abuse were covered up by the Home Office in the 1980s. The documents also reveal that the then director general of MI5 corresponded with the Cabinet Secretary in 1986 about an unnamed MP who was alleged to have a penchant for small boys". The letter from Sir Anthony Duff to Sir Robert Armstrong added: "At the present stage ... the risks of political embarrassment to the government is rather greater than the security danger." "The risk to children is not considered at all," Peter Wanless, chief executive of the NSPCC, and barrister Richard Whittam, said in a supplement to their review. The papers ... will be passed to an ongoing independent inquiry into child abuse within state and non-state institutions. Previously unreleased files also concern figures including Margaret Thatcher's parliamentary private secretary, the late Sir Peter Morrison, former diplomat Sir Peter Hayman and former minister Sir William van Straubenzee. The papers also contain material on allegations by a former British army intelligence agent, Colin Wallace, about the Kincora boys' home in Northern Ireland, which has long been at the centre of abuse claims. The Wanless review, published in November after the investigation of 114 missing Home Office files, could not rule out the possibility of files being destroyed as part of a coverup.
