I was 15 years old when I first heard the name Mandela, or Madiba, as he is fondly known in Africa. In apartheid South Africa he was public enemy number one. Shrouded in secrecy, myth and rumour, the media called him 'The Black Pimpernel'.

Nelson Mandela once said "I can't help it if the ladies take note of me; I'm not going to protest."

Nelson Mandela was just a human being, a person like other people, and everyone relaxed. Within a minute, that sort of thing about the leader and the lead, the gap was closed, and that's a rare thing.
