Sue Lawley's castaway this week is a playwright whose work has chronicled Britain's changing political landscape over the past 30 years. David Edgar was brought up in a leafy suburb of Birmingham, but was radicalised during the 1960s and has never looked back. In 1976, he examined the right-wing National Front movement in Destiny, a play for the RSC. It was his first award-winning play and the work of which to date he is the most proud.

His interest in theatre goes back to his childhood; his parents both had theatrical connections and his father even turned a garden shed into an elaborate theatre. It was here that as a boy he was to star in plays in which he cast himself in the leading role. Despite the shift of politics to the centre ground, he remains committed to the left-wing cause and to exploring the difference between utopia and reality. He also writes for TV and radio, and his plays are regularly performed on the international as well as the British stage.
