South African anti-apartheid campaigner Winnie Mandela has died aged 81, her personal assistant says.
Winnie Madikizela Mandela was the former wife of South Africa's first black president, Nelson Mandela.
The couple - famously pictured hand-in-hand as Mr Mandela walked free from prison after 27 years - were a symbol of the anti-apartheid struggle for nearly three decades.
However, in later years her reputation became tainted legally and politically.
Her family are expected to release a statement later today.
