Matt Smith will leave Doctor Who this year and hang up his sonic screwdriver and tweed jacket, after working on the show for four years.
The 30-year-old actor will make his last appearance as the Doctor in the 2013 Christmas special, when he will be written out the series and a new actor will take the helm of the TARDIS.
Matt Smith has recently been filming for the Doctor Who 50th anniversary special, in which he will star alongside his predecessor David Tennant, the episode will also mark the return of Billie Piper as Rose Tyler, and Welsh actress Joanna Page is playing a young Queen Elizabeth.
The episode, which airs in November, will also wrap up the mystery of the ‘impossible girl’, Clara Oswald.
Smith’s four year reign as the Doctor has been the most popular era in the show’s history, he has proven to be particularly popular with American fans, and the latest series of Doctor Who has reached an audience of 77 million people worldwide.
But ratings have taken a turn for the worse in the second half of series seven, with the show losing nearly a million viewers between the start and end of the series.
Critics were particularly harsh about the first few episodes of 2013, and BBC bosses are now looking to freshen up the show with a new Doctor, after also making changes to the production staff and announcing Welshman Brian Minchin as producer in April.
