Eskom head of generation Matshela Koko says he's determined to clear his name. He's taken to Twitter, to confirm his suspension after receiving a letter with fresh charges last night. Last Friday Koko won a Labour Court application preventing Eskom from firing him. Since the new board took over about two weeks ago, several Eskom executives have resigned or are being suspended. Yesterday, Chief Information Officer, Sean Maritz, was suspended pending an investigation into his dealings with consulting firm McKinsey.
