David Cameron has put pressure on the most senior official at the Home Office to find out what happened to a missing dossier of alleged paedophile activity at Westminster in the 1980s.
The Prime Minister said he understood the concerns that had been raised about the missing file which was handed to the then home secretary Leon (now Lord) Brittan by the Conservative MP Geoffrey Dickens.
"That's why I've asked the permanent secretary at the Home Office (Mark Sedwill) to do everything he can to find answers to all of these questions and to make sure we can reassure people about these events," he said.
The MP who raised the claims that a paedophile ring operated in Westminster during the 1980s said new allegations have now come to light.
Lord Brittan has defended his handling of a dossier alleging paedophile activity in Westminster when he was home secretary in the 1980s.
A 1980s dossier claiming paedophile activity at Westminster may have mysteriously gone missing but the questions still remain.
