Sue Lawley's castaway this week is the broadcaster and popular historian, John Julius Norwich. Closely associated with Venice, he talks about his love for the city and his battle to protect it from the rising waters of the Mediterranean. It's a passion he learnt from his parents - the diplomat and politician Duff Cooper and the beautiful socialite Lady Diana. As a boy he grew up surrounded by his mother's friends - artists and writers like Jean Cocteau and Noel Coward. Evelyn Waugh, too, frequently visited. But he was someone who his mother adored and his father barely tolerated.
