Baroness Butler-Sloss is to lead an independent inquiry into sex abuse claims at a range of British institutions, ITV News understands.
The 'wide-ranging' inquiry, announced yesterday by Home Secretary Theresa May, will see a panel of experts investigating whether institutions have taken seriously their "duty of care to protect children".
Baroness Butler-Sloss chaired the Family Court division of the High Court and the Cleveland Child Abuse Inquiry in 1988.
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.
