Sue Lawley's castaway this week is Dame Norma Major. In her book on the Prime Minister's residence, Chequers, she revealed how Neville Chamberlain would spend time measuring the girths of his favourite trees, and how Ramsay MacDonald chopped wood every morning dressed in plus-fours. She herself was uncomfortable there, and she remembers the loneliness and stress of being the country's First Lady. She says her love of music, and her work for charity helped her through the tough times.
