Oh, which to choose? The Fourth Doctor has been paired up with some of the most memorable companions in the show's history, from Tin Dogs to Time Ladies and even a man. All of them are wonderful, all of them much loved. The first, Sarah-Jane Smith, he inherited from his predecessor but he soon forged his own winning relationship with her. Don't forget the affable Harry Sullivan! Then there's Leela, savage warrior of the Sevateem who underwent a steady learning process right up until The Sunmakers when she became stupid again.

In the comic strip he was joined by Sharon, who helped him to defeat Beep the Meep, while his latest companion is Mrs Wibbsey, who joined him for the marvelous Hornets' Nest series of adventures.

But which of the fourth Doctor companions is your favourite?
