Submitting mislaid files on historical child sex abuse at Westminster is "the test of the Home Office's transparency," according to the MP who lead the campaign for the inquiry into allegations of peadophilia at Parliament.
Simon Danczuk told Good Morning Britain failure to hand in the missing files may lead to the Home Office's permanent secretary to be recalled to answer questions from the Home Affairs select committee.
The MP who has led the campaign for an inquiry into allegations of a high-level cover-up of child sex abuse has urged the former High Court judge appointed to oversee the investigation to stand down because she is too closely linked to the establishment.
Baroness Butler-Sloss has been tasked with heading the probe into whether alleged abuse by politicians and other powerful figures in institutions between the 1970s and 1990s was swept under the carpet.
Labour's Simon Danczuk claimed Baroness Butler-Sloss' position was compromised because her late brother, Sir Michael Havers, was attorney general at the time that many of the allegations relate to.
He told the BBC: "We want somebody in the chair that exudes confidence and that's not the case. She is part of the establishment and that raises concerns, and the relationship in terms of her brother, I think, is too close for comfort. I think that's the conclusion most people will reach.
"I think the Government should think again in terms of who they have appointed for this position."
"It beggars belief that that hadn't been considered in the first place," he added.
