President Jacob Zuma says former president Thabo Mbeki played a central role in selling the ANC to the rest of the world during apartheid.
He says Mbeki, together with other African leaders, led a concerted process of reviving institutions of governance and accountability in Africa through the African Union, the New Africa Initiative and later the New Partnership for Africa's Development.
Zuma was addressing a large crowd at the Sauer Park Stadium in Aliwal North in the Eastern Cape on Friday, as part of the ANC's centenary celebrations.
He paid tribute to Mbeki's history in the ANC at the side of former organisation presidents such as Oliver Tambo and Nelson Mandela.
