Peter Capaldi has admitted he's still not sure about his future as the Doctor.

Capaldi returns to BBC screens on Christmas Day and will star in the show’s 10th series next year. But series 10 will be the last to feature showrunner Steven Moffatt and Capaldi is yet to decide wether he’ll also be bowing out.

Speaking to Wales Online, Capaldi said: "I've been asked to stay on and I haven't made my mind up about that yet, mainly because I don't want to have to make that decision. I'm trying to avoid it!”.

The actor added that the greatest influence in his decision making will be "how good a time I was having".

"Doctor Who does take a lot of time, but it's a wonderful use of it," he continued. "It's special. I'm lucky enough to be in touch with other Doctors, and we all agree how extraordinary it is to be in this position.

“To decide to leave is a tough decision for everybody. [It was] very tough for Steven, so I'm just putting it off for as long as possible.

"I was happy with my life. I'd been very blessed already and there are things about doing the show that make life more complicated, certainly being so visible is a new and different way to be.”

"It's so delightful to be in this position. People aren't really seeing me any more. They see Doctor Who, so it's a fantastic place to be. It's also finite, so I'm enjoying as it unfolds,” he added.

This year’s Christmas special will see the Doctor travel to New York with Nardole (played by Matt Lucas), to try and save Manhattan from brain-swapping aliens.
