In his last filmed interview, murdered mining magnate Brett Kebble laid bare a plot within the ANC to oust former deputy president Jacob Zuma.

Independent producer Liesl Göttert interviewed Kebble for her four-part documentary The Zuma Media Trial, and describes him as "the only one with the guts to say what he thought on camera".

The series, which has never been broadcast, is purported on a promotional website to "uncover the reasons behind a politically orchestrated media campaign aimed at Zuma.

"The series exposes high-level political interference and unethical journalists who admit to having been compromised in covering the Zuma and arms-deal epic."

"The debate deepens when someone reveals who the different camps within the ANC might be, what their agendas are, and why it would be essential for them to keep Zuma from becoming the next president," said Göttert.

Asked yesterday if this "someone" was Kebble, Göttert said: "Yes, that's right".

"He explains the dynamics, nature and structure of two factions within the ANC that are at each other's throats. He names the individuals in both camps and describes one camp as 'the progressive elitists' and says they have no interest in broad-based empowerment, and use and abuse state apparatus to further their own ends."

Göttert added that Kebble described the second faction as a group that aligned themselves with Zuma, came from a grassroots background and were seen by the progressive elitists as taking the ANC backwards.

Göttert said the police had been in contact with her and she was expecting to be questioned more fully about her investigation.
