Westminster sex claim file found in archives

A file detailing "unnatural sexual" behaviour at Westminster in the early 1980s has been discovered among the National Archives.

The previously classified file was uncovered in Kew, south west London by a university lecturer last November.

Dr Chris Murphy told Sky News he was shocked to come across the document, entitled: "PREM19/588 - SECURITY. Allegations against former public [word missing] of unnatural sexual proclivities; security aspects 1980 Oct 27 - 1981 Mar 20."

He said: "I think I did a double-take and then started wondering what the potential implications of the title, which is a little vague, could be."

A Cabinet Office spokeswoman said: "In this case, the file was kept closed and retained as it contained information from the security services and advice from the Law Officers.

"These classifications are reviewed periodically."
