Nelson Mandela showing 'great improvement' - ex-wife Winnie
FORMER South African President Nelson Mandela is showing a "great improvement" in his health compared to a few days ago, his ex-wife, Winnie Madikizela-Mandela, said on Friday.
"I'm not a doctor but I can say that from what he was a few days ago there is great improvement," she told reporters outside Mandela's former home in the Johannesburg township of Soweto.
The former leader has been in hospital for most of the last month, where he remains in a serious condition.
President Obama is currently visiting the country, where he has described Mandela as a 'personal hero'.
