The actress Jenny Tomasin has died at the age of 75.
Tomasin played the role of Tasambeker, an employee of Tranquil Repose, in the 1985 Doctor Who story Revelation of the Daleks.
She was best known for her portrayal of the long-suffering Ruby in the London Weekend Television production Upstairs Downstairs, appearing in 41 episodes.

During the nineties she performed in many regional pantomimes, and in 2005 she returned to Emmerdale, this time playing Noreen Bell, a cantankerous villager, who was eventually killed off in July 2006.
