The pan-African telecommunications provider , which is headquartered in Johannesburg, said in a statement to shareholders on Friday that the board has "expressed its full support" for Mupita and for MTN's strategy.
The statement comes six days after the Sunday Times reported that an unspecified number of executives had threatened to resign after complaining that Mupita allegedly gave preferential treatment to a female executive.
"MTN shareholders are advised that the group board held a special meeting on Wednesday, 4 September to deliberate on a report by an independent law firm, assisted by counsel, tasked to verify allegations contained in an anonymous complaint against members of the MTN executive," it said in a statement issued via the JSE.
"The independent report stated that attempts to engage with the complainant were unsuccessful and found that there was no evidence of improper conduct by those cited in the complaint," it said, without naming anyone.
"In its deliberations, the board accepted the report finding and is of the view that the matter has been addressed and is now closed."
