The board of Transnet said it plans to dismiss CEO Siyabonga Gama after losing confidence in his ability to lead South Africa’s state-owned ports and rail company.

The board served Gama with a letter notifying him of the intention to terminate his employment and gave him 10 days to respond, it said in an e-mailed statement.

“The reasons provided to him by the board relate to alleged serious violations of his financial, procurement and fiduciary responsibilities as Transnet CEO,” the statement said. “As a result, the board had lost trust and confidence in Mr Gama’s ability to lead Transnet.”

President Cyril Ramaphosa’s administration is clamping down on graft and tackling poor management at state-owned companies, which are cash-strapped and pose an increasing risk to the nation’s finances. Executives at state power utility Eskom and South African Airways are among those to have been replaced.

Transnet initiated moves to suspend Gama and two other executives last month, amid a probe into their roles in procurement contracts.

The company squandered billions of rand and broke regulations when it altered the terms of a deal to buy 1 064 new locomotives, an investigation by law firm Werksmans Attorneys found. A separate national treasury-commissioned report found Transnet paid R509-million more for 100 locomotives after switching a supply contract to a Chinese rail company from Mitsui & Co of Japan. — Reported by Sam Mkokeli and Amogelang Mbatha, with assistance from Paul Burkhardt, (c) 2018 Bloomberg LP
