PIE files were stored in the Home Office

"The former leader of a pro-paedophile campaign boasted of storing the group’s files in the Home Office while he worked there."

"Steven Smith, 60, said he was given security clearance for his Whitehall job by Scotland Yard despite being chairman of the Paedophile Information Exchange."

"He worked as an electrical contractor monitoring security alarms at the Home Office for four years in the late 1970s and early 1980s."

"Smith later went on the run while facing charges over child abuse images. He was jailed in 1991 and again in 2011."

"In an obscure book published in 1986, he told how he was given a room of his own at the Home Office and used it to conceal PIE’s files."
