Steven Moffat has said it is too early for him to feel sad about stepping down from his roles on Doctor Who because “it’s hard to be wistful about something that might still kill you”.

The writer and executive producer will hand over the job to Broadchurch writer Chris Chibnall at the end of the next series in 2017.

However, he said he cannot yet feel nostalgic about the BBC One show, even though he knows he will be overwhelmed with emotion the day after he gives up the keys to the TARDIS.
