Theresa May has defended the decision not to question a whistleblower who claims the Home Office had offered a grant to the Paedophile Information Exchange (PIE).
Speaking to the Home Affairs Select Committee, Ms May said she would respond in writing to questions about the claims made to ITV News by former civil servant Tim Hulbert.
Ms May told the committee a prior review had found no evidence of either direct or indirect funding to the PIE from the department.
However, Labour MP Ian Austin criticised the decision not to interview Mr Hulpert in that review, and accused the Home Secretary of not having "looked into" it fully as she paused during his questioning.
The Baroness says she did not consider the "difficulties" caused by her background and family connections to the child sex abuse inquiry.
Questions have been raised of former High Court judge Baroness Butler-Sloss since her appointment last week.
22 police officers are now assigned to Operation Fernbridge - the probe into claims of a Westminster cover-up of sex child abuse.
