To celebrate its 25th birthday on 6 September, the world's longest running primetime medical drama, Casualty, is asking viewers to vote for their favourite episode from a shortlist of ten past classics.
From series 18's dramatic train crash to the sectioning of Ruth Winters (Georgia Taylor) in series 25; from series 12's mass motorway pile-up to Josh's (Ian Bleasdale) stabbing in series 15, viewers can go to the Casualty website to watch highlights from the top ten shortlisted episodes, enjoy the current casts' most memorable moments and vote for their favourite episode. And in a special online exclusive, Casualty favourite Derek Thompson explains how not to end up in a hospital's emergency department.

Launched in 1986 at a time when the NHS was under increasing pressure, Casualty featured the working lives of the staff in the emergency department of a large, inner-city hospital. The first series consisted of just 14 episodes and a pilot. Now a quarter of a century on, Casualty runs for 47 weeks a year and is still a stately staple of BBC One's Saturday night schedule, regularly pulling in over six million viewers in a much-changed TV landscape.
BBC Controller of Continuing Drama, John Yorke, says: "Very few television shows last two or three series and only a tiny handful last 25 years. During that time hundreds of medical dramas have come and gone, but Casualty has outlasted all of them."
