Public Protector urged to investigate Joburg mayor after controversial appointment By Karabo Ngoepe Share Johannesburg - Public Protector Busisiwe Mkhwebane has been urged to probe Joburg mayor Geoff Makhubo following his adviserâs appointment as acting chief executive of the Joburg Property Company (JPC). Mkhwebaneâs probe comes after businessman and politician Kenny Kuneneâs complaint about Ruby Mathangâs appointment to oversee one of the cityâs biggest budgets. Kunene contends that this represents a dangerous conflict of interest and gives Makhubo direct control of a major City-owned entity that oversees a multibillion-rand budget in the city. Mkhwebaneâs spokesperson Oupa Segalwe said the office had received the complaint and they would be assessing it.
