André de Ruyter

[1] De Ruyter published a book, Truth to Power, in May 2023, which detailed his three years at Eskom, and the level of pillaging, looting and political interference that contributed to the energy provider's downfall.

[5] That same month, it emerged that de Ruyter had been criticized by Gwede Mantashe, Minister of Mineral Resources and Energy and Chairperson of the ruling African National Congress.

[6] Ghaleb Cachalia, Shadow Minister of Public Enterprises of the Democratic Alliance, South Africa's official opposition, accused Mantashe of a "relentless campaign against a man who despite having one hand tied behind his back" attempted to fight corruption.

[7] On 22 February 2023, de Ruyter resigned with immediate effect,[8] and Chief Financial Officer Calib Cassim was appointed as interim CEO.

[10] He alleged that theft and graft were leading to losses of R1 billion per month from Eskom, that a senior ANC MP was involved, and the police investigating his poisoning "confused a dose of cyanide with a sinus complaint".
