Sue Lawley's castaway on this week's Desert Island Discs is dub poet Benjamin Zephaniah. As well as talking about his work as a performance poet often working in prisons or schools, Benjamin recalls a time when he was illiterate. He also remembers Nelson Mandela's request to meet him at seven o'clock in the morning to brief him on Margaret Thatcher.
