Caroline previously worked on The Ruby in the Smoke, which starred Doctor Who-alumni Billie Piper.
Speaking about Caroline's role, Moffat said, "The exec joining me on Doctor Who is Caroline Skinner - fresh from the wonderful Five Days, and still finishing up on a brand new show called The Fades (a fantasy horror series, written by Jack Thorne - I've seen episode 1, and it's BRILLIANT.) Somewhere between me laughing in a basement and choosing planets to invade, and Marcus Wilson raising armies, there has to be a Prime Minister actually running the whole thing. That's the job Piers Wenger and Beth Willis have been doing so wonderfully for the last few years. Now that Piers is off to movie land, that's the furnace Caroline will be walking into."
