Eskom cancelled coal-supply agreements and construction contracts valued at R11-billion, as the South African authorities crack down on crime at the State-owned utility, President Cyril Ramaphosa said. Litigation by Eskom has also had coal-supply agreements worth R3.7-billion declared invalid, and other coal and construction deals worth R10-billion have been set aside, Ramaphosa said in response to a question submitted by an opposition lawmaker in parliament.
