The Health department has appointed several forensic firms to investigate the Digital Vibes contract. Its Director General, Dr Sandile Buthelezi, says this is after alarms were raised last year about the issue. It's been alleged Health Minister Dr Zweli Mkhize benefited from this contract, which was awarded to some of his close associates. Dr Buthelezi has also been implicated in the investigation. One SA Movement leader, Mmusi Maimane, weighs in.
