Breaking : Nelson Mandela's Wife, Winnie Mandela Dies At 81

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.
