Peter Capaldi is quitting Doctor Who at the end of the year, the actor has confirmed.
The 58-year-old Glasgow-born star became the 12th Doctor in 2013, replacing Matt Smith, but says now he feels it's "time to move on".
Capaldi isn't the only person stepping down from the cult TV show this year - showrunner Steven Moffat will be replaced by Chris Chibnall (Broadchurch) for the next season.
"It (the new series of Doctor Who) will be my last... I feel it's time to move on," Capaldi said during a radio interview.
"I think Christmas 2017, I've just been told," Capaldi said, after being asked when he planned to leave.
"But I'm still Doctor Who. I've got a lot to do - we're doing epic stuff. I'm not done yet."
He described his time working on the show as "cosmic".
Before Doctor Who, Capaldi was best known as foul-mouthed communications director Malcolm Tucker in the political satire The Thick of It.
