Katy Manning appeared alongside the third Doctor Jon Pertwee as his young companion Jo Grant. A member of U.N.I.T., Jo Grant often found herself having to balance her loyalty to the Doctor with her subordinate role to the Brigadier. She was romantically linked with a number of prominent male characters including Captain Yates and the King of Peladon before eventually marrying a Welsh scientist. Katy is one of the longest serving cast members of Doctor Who having appeared in over 70 episodes.
Katy has also built a substantial following as a result of playing the Time Lady Iris Wildthyme in Doctor Who audio spin-offs. Her Doctor Who credentials have been strengthened even further recently with an appearance in the Sarah Jane Adventures and a key role in the black comedy audio Baker’s End featuring Tom Baker.
