Mineral Resources and Energy Minister Gwede Mantashe says that former Eskom CEO André de Ruyter "must not throw a stone in a bush and hope an animal will come out" – he must name the politicians he claimed were corrupt. Mantashe was briefing Parliament’s portfolio committee on mineral resources and energy on Friday. He was asked by MPs to respond to the claims by De Ruyter in a recent interview, in which it was alleged that "a top politician" was involved in corruption at Eskom. De Ruyter also claimed that when informed, the government did nothing about the corruption at Eskom and that the company was a feeding trough for the ANC. "All we need from our side is that he must not throw a stone in the bush. He must say Minister X has said this; Minister Y has asked for a cut and said and done this. That is all we want from our side because this thing of throwing a stone in the bush and hoping an animal will come running out [is wrong], he said. Mantashe also criticised De Ruyter for allowing Eskom to lose "market share" by allowing the performance of the coal-powered power stations to decline at a time when independent power producers also entered the market.
