It has been announced that the Doctor's legendary arch-enemies The Daleks will return for Doctor Who's 50th anniversary special in November.

The special episode on Saturday November 23 on BBC One sees the Doctor (Matt Smith) joined by two other Doctors, played by David Tennant and John Hurt.

The cast also includes Jenna Coleman, Billie Piper and Joanna Page.

Steven Moffat, lead writer and executive producer, said: "The Doctor once said that you can judge a man by the quality of his enemies, so it's fitting that for this very special episode, he should face the greatest enemies of all."
