British actress Caroline John, known to many for playing Doctor Who assistant Liz Shaw, has died at the age of 72.
John played Liz Shaw in four Doctor Who adventures in 1970, later reprising her role in 1983's The Five Doctors.
Both she and husband Geoffrey Beevers went on to work on several Doctor Who audio and straight-to-video spin-offs.
Born in 1940, John trained at the Central School of Speech and Drama and later toured with the Royal Shakespeare Company and the National Theatre.
As Elizabeth "Liz" Shaw, John made her first appearance alongside the newly-regenerated third Doctor in the story Spearhead from Space.
Her character witnessed the reawakening of an ancient race in The Silurians and stopped an insane scientist from cracking open the Earth's crust in Inferno.
She also got to drive Bessie, the Doctor's canary yellow roadster, despite the actress not having a driving licence at the time.
In recent years, John was seen in episodes of Doctors, Midsomer Murders and Silent Witness.
