BBC One controller Charlotte Moore has not ruled out the possibility of the next Doctor Who being a woman.

Moore, who is responsible for the strategy and all the shows commissioned on the flagship channel, said she would never "put a bar" on the direction in which producers wanted to take the programme.

"Peter Capaldi is a fantastic Doctor, and he's broken the mould. But I'd never put a bar on that," she told Radio Times. "The great thing about Doctor Who is that anything is possible."

In the revealing interview, Moore also discussed the controversial decision to sack Sir Tom Jones as judge on talent show The Voice.

Sir Tom spoke out at the time and said he was "unaware" he was being fired after four years on the show.

Moore rejected the idea that Sir Tom was badly treated and said it was simply "the way the pop industry works".
