It has been announced that Scottish actress Michelle Gomez has joined the cast of Doctor Who.

The 43-year-old actress, who is best known for her work in Green Wing, The Book Club and Bad Education, will play the Gatekeeper of Netherspere, when series 8 of the sci-fi drama returns on August 23.

Speaking about her casting Gomez said: "Well of course Peter Capaldi is our next Doctor, which makes complete sense. I'm thrilled to join him. Well, you would be wouldn't you?"

Lead writer and executive producer, Steven Moffat, added: “I've known Michelle for years, and I'm thrilled to welcome her to Doctor Who. She's everything we need - brilliant, Scottish, and a tiny bit satanic.”

Filming is well underway for Series 8 of Doctor Who. Guest stars confirmed to join Peter Capaldi and Jenna Coleman this Autumn include Frank Skinner, Ben Miller, Tom Riley, Keeley Hawes and Hermione Norris.

Doctor Who returns with feature-length opener Deep Breath on Saturday, August 23.
