The public inquiry into historic sex abuse claims could include the BBC, Home Secretary Theresa May has said.
Ms May said she would not exclude any body from investigation, which could also stretch to churches, and that political parties would not be outside the scope of the probe.
She added: "It is my intention that this should be a wide inquiry and that therefore it should be possible for it to look at not just state institutions.
"It has to look at every area where it is possible that people have been guilty of abuse and we need to learn lessons to ensure that the systems we have in place are able to identify that and deal with it appropriately."
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.
