Speculation as to who will play the next Doctor has been rife since David Tennant quit last October and today the BBC confirmed that the wait is nearly over. The identity of Tennant's replacement is to be announced tomorrow as part of a special edition of Doctor Who Confidential on BBC One.
Piers Wenger, the BBC's head of drama said: "We are so pleased to have been able to cast this person as the new Doctor. We believe the actor is going to bring something very special to the role and will make it absolutely their own."
During the Confidential special, to be aired tomorrow at 5.35pm, the actor playing the next incarnation will share their initial reactions to the news. The next doctor will replace Tennant for the fifth series in 2010.
Who do you think it could be?
