Johannesburg - Economic Development Minister Ebrahim Patel appointed Thembinkosi Bonakele as the new acting competition commissioner on Sunday, the department said.
Spokesperson Manelisi Wolela said Bonakele was appointed with effect from October 21, for a period of six months.
"Minister Patel's announcement follows the resignation of Shan Ramburuth as competition commissioner following an investigation undertaken into his fitness to hold office," Wolela said.
Bonakele had served as deputy commissioner of the competition commission and worked in all key divisions of the competition commission over the past nine years.
"The competition commission is a vital institution in our efforts to build a dynamic economy and it has a skilled and capable staff that will ensure the commission continues to perform its statutory functions.
"Mr Bonakele brings expertise in the field of competition policy and extensive knowledge of the commission and his presence will help the commission during the period when a new commissioner will be identified and appointed," the statement said.
