Line of Duty star Keely Hawes will play 'one of the greatest villains' ever in the new series of Doctor Who.
The 38-year-old actress will star as Ms Delphox who has been described as a 'powerful out of this world character with a dark secret'. Delphox will encounter the new Doctor (Peter Capaldi) and companion Clara (Jenna Coleman) when they arrive on a strange and puzzling planet.
Speaking about her casting Hawes, who will appear in the fifth episode of the new season, said: "I am delighted to join Doctor Who and to be working with this incredible team.
"Ms Delphox is a great character and someone I've had a lot of fun playing."
Doctor Who's lead writer and executive producer Steven Moffat added: "Anyone watching Jed Mercurio's amazing Line of Duty will know that Keeley Hawes is having one hell of a year.
"And now it's about to get even better as she achieves the greatest villainy yet attempted on Doctor Who - she plays a banker."
In addition to playing DI Lindsay Denton on Line of Duty, Hawes has also appeared in Spooks, Ashes to Ashes and Upstairs Downstairs.
