The BBC could face a full public inquiry into the Jimmy Savile sex abuse scandal if the corporation's investigations do not "get to the bottom" of the accusations, the Culture Secretary said.
The national broadcaster has launched an inquiry into the culture and practices at the corporation in the era of the late television star and it is also looking at the decision-making process which saw a Newsnight investigation into the Jim'll Fix it star's activities shelved.
Speaking about the probe, Maria Miller told The Sunday Telegraph: "The real challenge for the BBC is to make sure that the outcome of these reviews really gets to the bottom of these accusations.
"If the investigations are considered not to suffice because of issues around transparency, process or other such things, then a public inquiry remains an option."
Amid the fallout from the Jimmy Savile scandal the BBC is investigating nine allegations of sexual harassment among staff and contributors.
BBC boss George Entwistle has spent almost two hours taking questions from MPs about the corporation's handling of the Savile scandal.
Ex-BBC boss Mark Thompson has told ITV News he will help with any inquiry into the corporation and its handling of the Savile allegations.
