Lord Brittan has insisted that a 1980s file that made allegations of child abuse in Westminster was dealt with properly and handed to the appropriate authorities.
Documents released by the Home Office have shown that Lord Brittan wrote to Mr Dickens the following March saying the Director of Public Prosecutions (DPP) had assessed the material as worth pursuing and it was "now being passed to the appropriate authorities".
The missive features in an independent review commissioned by the Home Office last year that also reveals it has "not retained" the dossier.
"The review found information had been dealt with properly. It also disclosed that material received from Mr Dickens in November 1983 and January 1984 had not been retained." Lord Brittan said.
