The security services are facing questions over the cover-up of a Westminster paedophile ring as it emerged that files relating to official requests for media blackouts in the early 1980s were destroyed. Two newspaper executives have told the Observer that their publications were issued with D-notices - warnings not to publish intelligence that might damage national security - when they sought to report on allegations of a powerful group of men engaging in child sex abuse in 1984. One executive said he had been accosted in his office by 15 uniformed and two non-uniformed police over a dossier on Westminster paedophiles passed to him by the former Labour cabinet minister Barbara Castle. The other said that his newspaper had received a D-notice when a reporter sought to write about a police investigation into Elm Guest House, in southwest London, where a group of high-profile paedophiles was said to have operated. Theresa May, home secretary, this month told the Commons that an official review into whether there had been a cover-up of the Home Office's handling of child-abuse allegations in the 1980s ... was prompted by the discovery that 114 Home Office files related to child abuse in the 1980s had gone missing. The two journalists, Don Hale, the former editor of the Bury Messenger, and Hilton Tims, news editor of the Surrey Comet between 1980 and 1988, both recall their publications being issued with D-notices around 1984.
