Eskom chairman Ben Ngubane says it is “impossible” that he and CEO Brian Molefe could be implicated in an alleged corrupt coal deal within the parastatal.

Ngubane was responding to claims on Tuesday by former mineral resources minister Ngoako Ramathlodi‚ who reportedly said the two men tried to force him to suspend the mining licences of coal supplier Glencore so the Gupta family could buy the Optimum coal mine from them.
