Fans of the BBC One show were rocked by the departure of the Doctor's companion Clara Oswald (Jenna Coleman) in the last series but Peter Capaldi - who plays the titular character - has teased they are putting a lot of thought into securing just the right person as her replacement.

He said: "We've just had some brief talks about it, we haven't actually chosen someone yet - that I know of.

"Perhaps someone has been chosen but I would expect that I would meet them before we finalised all that. So we're looking for someone different..."

The 57-year-old actor also admitted it was "quite challenging" to film an episode on his own following Jenna's departure.

He added to RadioTimes.com: "The [episode] where I was on my own was quite challenging because I thought people would get tired of my face and all my tricks.

"But in a way it was great to do an episode - I mean this in the nicest possible way - with no other actors because it meant I became very much closer with the crew. The crew are fantastic and I have a great relationship with them anyway, but to be with them all the time was lovely."
