New director general Tony Hall: BBC can overcome crisis

Tony Hall, the new director general of the BBC, has said he is confident the corporation can get through a "really tough few weeks".

Lord Hall, chief executive of the Royal Opera House and the BBC's former director of news, said he cared passionately about the organisation.

"I am absolutely committed to our news operation as a world-beater," he said.

His appointment follows the resignation of George Entwistle in the wake of the Newsnight Lord McAlpine row.
