Theresa May has defended the appointment of Baroness Butler-Sloss to the wide-ranging inquiry into allegations of child abuse at a number of institutions saying she had no regrets about the decision.
Labour MP Tom Watson has told ITV News "the law has to be seen to be done" after Baroness Butler-Sloss' decision to stand down from leadership of an inquiry into allegations of child abuse.
Mr Watson, who campaigned for an inquiry into the claims, said even though Baroness Butler-Sloss "would not be compromised" by any potential relationships she had, her position as chair of the probe would have made it harder for victims to come forward.
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.
