Disgraced former health minister Zweli Mkhize may have resigned, but he can still be criminally charged for his role in the health department's awarding of a R150 million communications contract to Digital Vibes - a company he is closely linked to.
The Special Investigating Unit (SIU) says Mkhize may have committed acts of criminality and caused irregular and wasteful expenditure by approving budgets for the contract.

This emerged on Wednesday when the unit briefed the Standing Committee on Public Accounts (Scopa) on the contract.
According to a presentation by SIU head, advocate Andy Mothibe, the allegations against Mkhize relate to his failure to execute his function in compliance with the Constitution.
