From political parties to civil society, social media is awash with tributes to the struggle icon, Ahmed Kathrada, who died early on Monday morning.
The anti-apartheid activist died after a short illness, and a memorial service has been arranged for Tuesday morning.
The African National Congress said his life was a lesson in humility, tolerance and resilience.
The Thabo Mbeki Foundation said that he was so committed to principle, he refused to be broken by harassment, torture or imprisonment.
