Theresa May will set up an independent investigation into the disappearance of files handed to the Government that allegedly related to claims of organised child sex abuse at Westminster in the 1980s.
A Home Office spokesman said:
Nothing is more important than the protection of children from abuse. That is why, following allegations that in the 1980s the Home Office failed to act on evidence of child abuse, the Permanent Secretary ordered an investigation by an independent expert in February 2013.
That investigation reported last year and its executive summary was published on 1 August 2013. During the course of the investigation, 13 items of information about alleged child abuse were found.
The police already knew about nine of those items, and the remaining four were passed to the police immediately. It is important that we do not pre-empt or prejudice any related police investigations.
May is set to make a statement in Parliament this afternoon that will address the Home Office's response in the 1980s to the files and also the "wider issue" of the response by public bodies and other institutions.
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.
