Nelson Mandela is making "steady progress" while undergoing treatment in hospital for a recurrent lung infection, South Africa's presidency said on Friday.
""Mandela is in good spirits and enjoyed a full breakfast this morning. The doctors report that he is making steady progress. He remains under treatment and observation in hospital." it added in a statement, without giving further details about the health of the 94-year-old anti-apartheid leader.
Mandela, who became South Africa's first black president in 1994, has been mostly absent from the political scene for the past decade, but remains an enduring and beloved symbol of the struggle against racism.
He is renowned at home and abroad for spending 27 years in prison fighting the last bastion of white rule in Africa and then promoting the cause of racial reconciliation.
Mandela has been frail and in poor health for several years. He was admitted briefly to hospital earlier this month for a check-up and spent nearly three weeks in hospital in December with a lung infection and after surgery to remove gallstones.
As he has receded from public life, critics say his ruling African National Congress (ANC) has lost the moral compass he bequeathed it when he stepped down as president in 1999.
Under such leaders as Mandela, Walter Sisulu and Oliver Tambo, the ANC gained wide international respect as it battled white rule. Once the yoke of apartheid was thrown off, it began ruling South Africa in a blaze of goodwill from world leaders who viewed it as a beacon for a troubled continent and world.
Almost two decades later, this image has dimmed as ANC leaders have been accused of indulging in the spoils of office, squandering mineral resources and engaging in power struggles.
Mandela spent much of last year in Qunu, his ancestral village in the poor Eastern Cape province. But since his release from hospital in December he has been at his home in an affluent Johannesburg suburb, closer to sophisticated medical facilities.
