Doctor Who Live: The Next Doctor

The BBC have announced that the next star of Doctor Who is to be revealed this coming Sunday evening in a special programme to be broadcast live on BBC One at 7:00pm, and simulcast by BBC America.

Update Friday Canadian channel SPACE have confirmed they will also broadcast the live show.
Update Saturday ABC Australia have also confirmed they will broadcast the live show.

Doctor Who Live: The Next Doctor is to be presented by Zoe Ball, and is expected to feature previous Doctors, companions, special guests and 'celebrity' fans, leading up to the reveal of who has won the coveted role. Charlotte Moore, the Controller of BBC One, said:
In order to keep the half-hour show and the announcement under wraps, the BBC promoted it last week as an entertainment pilot that would pay tribute to 50 years of Doctor Who. For television schedules they instead listed a repeat of Celebrity Mastermind in the timeslot - a similar tactic was employed back in 2009 with Matt Smith's announcement, when the scheduled The Ten Doctors turned out to be a smokescreen for The Eleventh Doctor. BBC America, meanwhile, have had a repeat of The Eleventh Hour scheduled for Sunday afternoon.

Smith will also feature in Sunday's broadcast, lending advice on what it takes to play the Doctor; the show will also include interviews with Jenna Coleman and executive producer Steven Moffat, who said:

The casting process itself has been a well-kept secret, with plenty of speculation as to who will take on the role. Ben Stephenson, the Controller of BBC Drama Commissioning, commented:
As reported on Wednesday, established names such Peter Capaldi, Ben Daniels, Chris Addison, Rory Kinnear and David Harewood have all been popular choices with the betting public - though it is just as likely that a previously unconsidered name will be revealed come Sunday evening, as with Smith in 2009.
