The good name of Nelson Mandela is again being used for purposes of someone else’s vanity. The South African elder statesman has denied that he wrote a foreword attributed to him in a book by Congo Republic President Denis Sassou-Nguesso. The Mandela Foundation said it would take appropriate action on behalf of the former Nobel peace laureate. The foreword quotes Mandela as saying Sassou-Nguesso was one of Africa's great leaders, and that he has worked tirelessly to free oppressed people from their chains. Nothing could be further from the truth.
