The writer Graeme Curry has died at the age of 61.
Graeme Curry wrote the 1988 Doctor Who story The Happiness Patrol, starring Sylvester McCoy as The Doctor and Sophie Aldred as Ace.
The story featured Sheila Hancock as Helen A, a character now acknowledged to be based on the then Prime Minister, Margaret Thatcher. The story is unique in Doctor Who stories for being mentioned in the Archbishop of Canterbury's Easter Sermon when Dr Rowan Williams referenced the story in his 2011 message.
The Happiness Patrol was the first television commission for Graeme Curry after he pitched an idea to script editor Andrew Cartmel about a planet where it was a crime to be unhappy. He went on to write for EastEnders as well as The Bill and the Radio 4 drama Citizens.
