After hours of speculation, the identity of Doctor Who's arch Nemesis, the Master can now be exclusively revealed.
The person destined to don the black cloak and pointy beard in season 3 of the cult sci-fi show is non other than Joan Sims.
Best known for her appearances in over 800 'Carry On' movies, Miss Sims has spent the last few years living in relative obscurity, having died in 2001.
Close friend and psychic Derek Akorah said that Miss Sims was 'over the moon' at being asked to appear in the show as such an iconic character and was looking forward to starting work in Cardiff later this month.
Joan's last appearance on the show was back in 1986 when the Doctor was played by Ronald McDonald.
