South Africa's ailing anti-apartheid hero Nelson Mandela started his second month in a Pretoria hospital on Tuesday (July 9).

The former President was admitted to hospital on June 8 and is receiving treatment for a recurring lung infection.

The South African government said that Mandela remained in a "critical but stable" condition, following a visit to the hospital by current President Jacob Zuma last Thursday (July 4).

The failing health of 94-year-old Mandela, a figure admired globally as a symbol of struggle against injustice and racism, has reinforced a realisation that the father of the post-apartheid South Africa will not be around forever.

While he lies in hospital, a row over grave sites has split Mandela's family.
