Nelson Mandela was host to a five-hour pop concert in Cape Town in a benefit to fight AIDS. “Mr Mandela, 85, who watched the show alongside his wife Graca Machel and US TV presenter Oprah Winfrey, has said Aids is a bigger challenge than apartheid. In South Africa there are more people living with HIV/Aids than anywhere else in the world, and globally the number of those infected is now more than 42 million.”
