The Democratic Alliance has laid a charge of corruption against Eskom bigwig Matshela Koko.
The charge relates to at least two transactions the power utility entered into while Koko was head of generation capacity.
Koko was last week reportedly cleared of any wrongdoing at Eskom.
He was on suspension and went through a disciplinary hearing.
Eskom’s spokesman Khulu Phasiwe, however, says the outcome of the disciplinary hearing is being studied by the Board and would not confirm reports that Koko was cleared.
Koko’s charges relate to a R1 billion contract awarded to a company with links to his stepdaughter.
He was, however, reportedly cleared of not declaring this conflict of interest.
The DA says Koko’s disciplinary hearing was a sham and the charges need to be probed by the Hawks.
The party also wants Koko’s involvement in the approval of a R600 million prepayment to Tegeta.
The money was approved for coal purchases but it was discovered that it was used to buy Optimum Mine from Glencore.
The DA laid a criminal complaint at the Cape Town central police station.
DA shadow minister of public enterprises Natasha Mazzone says, “The charges relates to transactions dealing with impulse trading, most significantly it’s a billion rand that we’re dealing with there in terms of Mr Koko’s stepdaughter who was involved at the time with a conflict of interest there and also with the possibility that Mr Koko was involved in a R600 million upfront payment to Trillian Capital. We need the Hawks to look into that matter too.”
