Sue Lawley's guest this week is Peter Melchett. The executive director of Greenpeace, he has recently hit the headlines for his active opposition to genetically modified crops. Once a pillar of the establishment, Lord Melchett was a rising politician in Jim Callaghan's Labour government before he became interested in green issues. He did though shock his colleagues in the Northern Ireland office, when he admitted listening to the pop group The Boomtown Rats.
