Saki Macozoma, a former Robben Island prisoner, met Nelson Mandela there in 1977

Nelson Mandela, one of the towering figures of our times - a man who helped shape our modern world, has died. He'd been ill for some time.
He fought against and eventually defeated the apartheid system, under which a white minority ruled. He spent 27 years in jail before emerging to become the country's first black leader.
