Tony Hall has started his first day as director general of the BBC, saying he is confident about the future of the corporation.
He said the BBC's role "is even more important now" than when he first joined it "many decades ago".
Lord Hall returns to the corporation in the wake of the Jimmy Savile sex abuse scandal, which led to the resignation of his predecessor George Entwistle.
He said the BBC was "learning the lessons" from recent "difficult times".
