Nelson Mandela Foundation calls for probe into state capture

Speaking during a media briefing where the foundation also reiterated its call for President Jacob Zuma to step down, the board of trustees' chairperson Professor Njabulo Ndebele said the current self-serving networks need to be uprooted.

"We referred not to individual leaders because it would be a mistake to focus on one leader. A network of corruption has been set up," he says.

Ndebele says it isn't easy to ask the president to step down, but that the time has come for him to listen to the people and leave office.

Ndebele says they realise that the removal of one person won't solve all the country's problems.

"Removing one person still leaves the corrupt network intact," he says.

Businessman, politician and anti-apartheid activist Tokyo Sexwale also joined the call, saying it took them a while to come to the conclusion that the president must go.

"It has taken us a while - after a lot of analyses - to say that the president must follow his conscience," Sexwale says.

He believes the time has come for Zuma to listen to the voices of the people who elevated him to office.

"Those people are now saying perhaps it is time to reconsider his position and we have come to that position - not lightly," he says.
