Doctor Who’s 12^th doctor will be revealed in a special live programme on Sunday, the BBC has announced.

The show, presented by Zoe Ball, will feature an interview with the new lead, as well as 11th Doctor Matt Smith and executive producer Steven Moffat.

“The decision is made and the time has come to reveal who’s taking over the Tardis,” Steven Moffat said.

“For the last of the Time Lords, the clock is striking twelve.”

Doctor Who Live: The Next Doctor is on BBC One at 7 p.m. on August 4.

According to the official announcement, Zoe Ball “will unveil the 12th Doctor in the first ever interview in front of a live studio audience set against the backdrop of a swirling vortex, amongst Daleks and the Tardis”.

Matt Smith, who has played the Time Lord since 2010, announced in June that he would be bowing out in this year’s Christmas special.

The announcement sparked much speculation about who might take over, with Peter Capaldi, Ben Daniels, Rory Kinnear and Ben Whishaw among the bookies’ favorites.

Doctor Who marks its 50th anniversary on 23 November with a special episode, starring Matt Smith, David Tennant and John Hurt as the Doctor.

Billie Piper will return as Rose Tyler, while Jenna Coleman will continue as Clara Oswald.

The episode will also see the return of the Daleks and the Zygons.
