The ex-wife of ailing Nelson Mandela on Friday said that the anti-apartheid icon's condition had improved in recent days, but he was still "unwell." "From what he was a few days ago, there is great improvement, but clinically he is still unwell," Winnie Madikizela-Mandela said near the couple's old house in Soweto.

Madikizela-Mandela tirelessly campaigned for Mandela's release during his 27-year imprisonment under apartheid, becoming a household name in her own right. But her image was tarnished by a series of scandals, including her links to the kidnap and murder of a young activist and a 2003 fraud conviction.
