Episodes Broadcast: 2006, 2008-2010, 2023

Having trained at the Bristol Old Vic, Jacqueline King began appearing on television in the early Eighties, on programmes such as The New Adventures Of Lucky Jim, Andy Robson and Late Expectations. She could more frequently be found in the theatre; King often worked abroad, but amongst her domestic productions were a number of plays written and directed by Alan Ayckbourn. Rare television roles during the Nineties included Hetty Wainthropp Investigates, but King increasingly accepted work on the small screen after the turn of the century. She had a recurring role in 55 Degrees North, and could also be seen in shows like Casualty and The Bill. A longtime fan of Doctor Who, King began appearing in audio dramas for Big Finish Productions. The first of her many roles for the company was as an alternative version of companion Barbara Wright for Deadline, a 2003 release in the Doctor Who Unbound range.

In 2006, King was cast as Sylvia Noble -- mother to Catherine Tate's Donna Noble -- in The Runaway Bride, a Christmas special starring David Tennant as the Tenth Doctor. She assumed that the small part would be a one-off appearance, and moved on to a recurring role in four installments of Doctors. However, when Tate agreed to return to Doctor Who for the 2008 season, King was also invited back. Given the opportunity to imbue Sylvia with far more depth, and acting opposite the legendary Bernard Cribbins as her on-screen father, Wilfred Mott, she would make eight Doctor Who episodes over the next couple of years. King ultimately bowed out alongside Tate, Cribbins and Tennant in 2010's The End Of Time.

During the next decade, King appeared in shows like Coronation Street, Midsomer Murders, Bounty Hunters and Silent Witness. She also continued her association with Big Finish, eventually reprising the role of Sylvia Noble starting with 2018's Wild Pastures. Her credits in the Twenties included The Duchess and Adult Material. King reprised the role of Sylvia Noble in 2023's The Star Beast and The Giggle, as part of Doctor Who's sixtieth anniversary celebrations.
