Longtime Doctor Who showrunner Steven Moffat will be stepping down as writer and executive producer after season 10, the BBC has confirmed.

Revealed by the official Doctor Who twitter account, Broadchurch writer and producer Chris Chibnall will be taking his place.

Moffat is the second showrunner in the show’s history since the series revamp in 2005, taking over for Russell T. Davies.

According to the BBC, season 10 of the show will not air until spring 2017, where Moffat’s final 12-part season will air. Chibnall’s debut will not happen until sometime in 2018.

Only one episode of the acclaimed science-fiction series will air in 2016 and that will be the Christmas special. It is still unclear if the current Doctor, played by Peter Capaldi, will have a new companion. Actress Jenna Coleman wrapped up her final season as Clara Oswald last season and there’s been no news yet on who will be playing the Doctor’s next partner-in-time.

New showrunner, Chibnall, is no stranger to the “Whoniverse,” having written numerous episodes of Doctor Who and the spin-off series, Torchwood, as well as working closely with Who alum David Tennant in Broadchurch.

Moffat said of his decision to quit: “Feels odd to be talking about leaving when I’m just starting work on the scripts for season 10, but the fact is my timey-wimey is running out. While Chris is doing his last run of Broadchurch, I’ll be finishing up on the best job in the universe and keeping the TARDIS warm for him. It took a lot of gin and tonic to talk him into this, but I am beyond delighted that one of the true stars of British Television drama will be taking the Time Lord even further into the future. At the start of season 11, Chris Chibnall will become the new showrunner of Doctor Who. And I will be thrown in a skip.”

Doctor Who returns to television for the annual Christmas episode this December and Moffat’s final season will air in 2017, with Chibnall taking over the following year.
