have confirmed that the Twelfth Doctor is to be announced this Autumn, prior to filming of the 2013 Doctor Who Christmas special, read on for further details:
BBC insiders have told RadioTimes.com that filming on the Christmas special - to be followed by the full series - will not take place until the autumn - probably August, or even September.
According to sources the identity of the Twelfth Doctor is almost certain to be announced just prior to filming, which means that it is very likely that the new incarnation of the Time Lord will not be unveiled until late summer.
Initially the BBC had hoped to begin filming the Christmas special earlier, with some sources suggesting July as a potential date.
“Suffice to say we are completely on track” said a spokeswoman.
Doctor Who returns to BBC One and BBC One HD later this year in the show's 50th anniversary special, before the new Doctor is unveiled in the annual Christmas special.
