This after revelations that his family may have benefited from proceeds of a R150m tender his department awarded to communications company Digital Vibes. The company employed the minister's former spokesperson and alleged family friend, Tahera Mather, and his former assistant, Naadhira Mitha. “The DA will be laying criminal charges against Minister Mkhize and health director-general Dr Sandile Buthelezi with the SA Police Service (SAPS) tomorrow. Over and above the SIU probe, a criminal investigation needs to ensue,” said the DA.
