Call The Midwife star Emerald Fennell will play Camilla Parker Bowles in the third series of The Crown.

She joins the previously announced Olivia Colman, Tobias Menzies, Helena Bonham Carter, Jason Watkins, and Josh O’Connor.

As well as being an actress, Fennell will also be head writer on the second season of Killing Eve.

“I’m absolutely over the moon, and completely terrified, to be joining so many hugely talented people on The Crown,” Fennell said. “I absolutely love Camilla, and am very grateful that my teenage years have well prepared me for playing a chain-smoking serial snogger with a pudding bowl hair cut.”
