The makers of Doctor Who have selected their new Doctor and all will be revealed on a special live show on BBC One this Sunday.
Doctor Who Live: The New Doctor is a half-hour special show to be hosted by Zoe Ball which will feature guests, Doctors old and new as well as the big reveal of the 12th Doctor.
Both the current Doctor Matt Smith and lead writer Steven Moffat will be interviewed on the show.
Moffat said "The decision is made and the time has come to reveal who's taking over the TARDIS. For the last of the Time Lords, the clock is striking twelve."
Controller of BBC One Charlotte Moore said “BBC One is the home of big live events and this special live show is the perfect way to reveal the identity of the next Doctor and share it with the nation. The Doctor is a truly iconic role and I'm more than excited about the booking."
Ben Stephenson, Controller of BBC Drama Commissioning, added "We can't wait to unveil the next Doctor with everyone live on BBC1 on Sunday night. Amongst all the speculation and betting, there has been lots of fun and intrigue at work as we've been using the codename Houdini as a decoy!
"It's the biggest secret in showbiz, even those working with the new Doctor on other projects at the moment have no idea they are in the presence of the 12th incarnation."
The show will be on BBC One at 7pm this Sunday.
