Eskom’s departing chief says criminal networks thwarted his fight against rolling blackoutsJOHANNESBURG—One Monday last month, the chief executive officer of South Africa’s state-owned power company Eskom Holdings SOC Ltd., André de Ruyter, woke up for his 5 a.m. gym routine, then headed to an off-site meeting with the chairman of the board. Hours later, he lay shaking in a clinic bed. Blood tests viewed by The Wall Street Journal showed that he had ingested cyanide.
Now, the South African government is looking for a successor to Mr. de Ruyter, who says he handed his resignation to the Eskom board chairman hours before he started feeling nauseous and confused in his office on Dec. 12. Mr. de Ruyter says he suspects the cyanide was added to a cappuccino he drank from his personalized mug at his office.
