Lawyers representing alleged victims of sexual abuse welcomed Theresa May's announcement of an inquiry into the duty of public bodies to protect children from paedophiles.
Alan Collins, a lawyer at Slater and Gordon which represents 176 alleged victims of abuse by Jimmy Savile, said: "All the victims we represent will welcome today's announcement.
"It is vital we get to the bottom of how abuse inside institutions was allowed to go unchallenged for decades."
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.
