Lead writer and executive producer Steven Moffat has announced he will depart the show at the end of the upcoming tenth season.

"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," Moffat writes in a statement.

Chris Chibnall, the producer of hit British drama Broadchurch will replace Moffat, who adds, "It took a lot of gin and tonic to talk him (Chibnall) 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."
