Johannesburg – Ailing former president Nelson Mandela is still in a critical but stable condition, the presidency said on Monday.

“We remind all South Africans to begin planning for Madiba’s birthday on the 18 July,” President Jacob Zuma said in a statement.

“We must all be able to do something good for humanity on this day, in tribute to our former president.”

Zuma thanked everyone who kept Mandela and his family in their thoughts and prayers.
