Quesitons have been raised about the true state of Nelson Mandela's health since he was discharged from hospital.
On Monday the former president of South Africa was described as being "in good health and good spirits" after a visit by a delegation from the African National Congress.
Many have questioned the ANC's verdict on Nelson Mandela's health
President Jacob Zuma and other party leaders visited the 94-year-old at his Johannesburg home, Reuters reported.
In a statement on its website, the ANC said: "After receiving a briefing from the medical team, the National Officials are satisfied that President Mandela is in good health and is receiving the very best medical care.
"President Mandela is keenly aware of the goodwill that has been outpouring from the peoples of the globe as befitting his status as our icon. The African National Congress thanks all South Africans and the international community for keeping President Mandela in their thoughts and prayers."
However, some were not so enthusiastic as the ANC about Mr Mandela's health after seeing photos and footage of the visit.
In the video, Mr Mandela seen looking grey-skinned and unsmiling, sits in an armchair with his head propped up by a pillow and his legs covered by a blanket.
President Zuma jokes with the other ANC officials and members of the Mandela family while Mr Mandela stares straight ahead, unresponsive.
After trying to hold Mandela's hand but getting no response, Mr Zuma is forced to cover it with his own.
The former anti-apartheid icon has suffered a number of health scares in recent months, the latest being more than a week in hospital for pneumonia.
Mr Mandela has suffered from lung problems since he contracted tuberculosis during his 27 years in prison as a political prisoner.
