Former Eskom CEO Matshela Koko has claimed at the State Capture Commission in Johannesburg that he is shocked that the account of an anonymous businessman - to whom he had been sending emails - actually belonged to Gupta associate Salim Essa. The commission provided detailed evidence showing Koko several emails he had sent to an info portal address which belonged to Essa. Koko last month denied at the commission that he had met with the Guptas and their associates. Koko claimed to Deputy Chief Justice Raymond Zondo that he thought the email address belonged to former Eskom Chair Ben Ngubane. Koko says he received the email address from then Eskom Company Secretary Suzanne Daniels in 2015.
