Who is new BBC chief Tony Hall?
The chief executive of the Royal Opera House and the BBC's former director of news, Tony Hall, has been appointed the corporation's new director general.
BBC Trust chairman Lord Patten said Lord Hall was "the right person to lead the BBC out of its current crisis".
The appointment follows the resignation of George Entwistle earlier this month after just 54 days in the job.
Mr Entwistle quit on 10 November after a Newsnight report led to Lord McAlpine being wrongly accused of child abuse.
The BBC's Robert Peston talks about Lord Hall's career.
