Mandelas widow furious over book on his last days
You're referring to the controversy surrounding the book "Mandela: The Authorized Biography" by Anthony Sampson, which was published in 2000. The book was written with the cooperation of Nelson Mandela and his family, but it has been criticized for its portrayal of Mandela's final days.
According to reports, Winnie Madikizela-Mandela, Mandela's ex-wife, was furious over the book's depiction of Mandela's relationship with his second wife, Graça Machel, and the way it portrayed her own role in Mandela's life. She felt that the book was inaccurate and unfair, and that it had been written to tarnish her reputation.
The controversy surrounding the book led to a public feud between Winnie Madikizela-Mandela and Graça Machel, with both women making public statements criticizing each other. The feud ultimately led to a rift between the two women, and they never reconciled before Winnie Madikizela-Mandela's death in 2018.
It's worth noting that the controversy surrounding the book was not limited to Winnie Madikizela-Mandela's criticisms. Other critics have also accused the book of being overly critical of Mandela's leadership and of portraying him in a negative light. However, the book remains an important historical account of Mandela's life and legacy, and it has been widely praised for its detailed and nuanced portrayal of his experiences.
