The show runner will all know and love... will be leaving at the culmination of series 10 in 2017. Replacing him will be Chris Chibnall most know for the creation of Broadchurch. Chibnall has a few Who episodes already under his belt including 42 and The Hungry Earth.
I for one am looking forward to this change in leadership. Broadchurch is absolutely amazing and his previous Who episodes are pretty solid.
