In a special episode of Doctor Who Confidential that will get its debut on BBC One today, the name of the actor to play the eleventh Doctor will be revealed. The episode of Confidential will take a look at the past 10 Doctor's, and it will feature an interview with the actor who is replacing David Tennant. You can view a trailer for the programme below;

Make sure you tune in at 5.35pm on BBC One today to watch the episode of Confidential, entitled The Eleventh Doctor. The programme was previously named The Ten Doctor's but now has been changed, but maybe the BBC had planned to do that the whole time. Make sure you come back to the Tardis Base shortly after the programme finishes for some coverage. Who do you think the eleventh Doctor will be?
