Matt Smith has admitted he's "sad" Steven Moffat is leaving Doctor Who after the next series.

The Eleventh Doctor admitted the showrunner has done so much for the series and he feels "very privileged" that he got to work with him.

During a press tour for his upcoming film Pride and Prejudice and Zombies, Smith said: "I'm sad he's leaving Doctor Who. He's done so much for it and so much for me."

He added: "He pretty much is Doctor Who, but the show will always endure and there's a wonderful writer coming in and as always, it's about regeneration and reinvention of things.

"But he has done so much for the show and I feel very privileged that I got to work with, what I think, is the greatest writer."

After the 10th series of Doctor Who airs in 2017, Moffat will step down and Broadchurch's Chris Chibnall will take over writing duties on the BBC One series.
