The castaway in Desert Island Discs this week is Jimmy Knapp, General Secretary of the Rail, Maritime and Transport Union. He'll be talking to Sue Lawley about his Scottish childhood, his poor, working-class background and his rise from signalman to one of the most powerful and controversial trade union leaders in the country. He'll also be discussing his views on public ownership, the future of Clause 4 and such personal matters as his Scottishnesss, love of Spain and his much-maligned dress sense.
