Former health secretary Andrew Lansley has insisted an investigation into claims of sexual abuse by Jimmy Savile on NHS premises would be handled "independently and effectively."
Former barrister Kate Lampard will oversee the investigations into the disgraced DJ at Stoke Mandeville Hospital, Broadmoor and Leeds General Infirmary.
Labour's Barbara Keeley asked "why the Department believes that internal reviews overseen by NHS insiders are sufficient when we've got abuses against children and vulnerable patients being alleged".
But Mr Lansley, now Leader of the House, replied: "I would say, knowing Kate Lampard, I am sure she will conduct her investigations in relation to the NHS independently and effectively."
Jimmy Savile was questioned as a suspect by police investigating the Yorkshire Ripper, according to a retired police officer.
Jimmy Savile's nephew has spoken of the emotional turmoil his family is going through in the wake of the sex abuse allegations.
A colleague of Jimmy Savile allegedly raped a woman on BBC premises in 1970, ITV News has been told.
