Following the publication of the Pollard Report, which said Newsnight editor Peter Rippon's decision to drop the programme's Jimmy Savile investigation was flawed, he said:
Of course, like everyone at the BBC connected with this case, I will learn lessons from what has happened, as I move on with my career.
The BBC itself has an overriding responsibility to foster and support good journalism, and to respond proportionately when that journalism is challenged.
Nick Pollard has raised questions about whether the BBC has been able to do this, and I agree with him that change is necessary.
The decision to drop the BBC Newsnight investigation into the Jimmy Savile sexual abuse claim was "flawed", according to a review.
A damning report into the BBC's Jimmy Savile investigation has revealed George Entwistle was previously warned about his "darker side".
