The Special Investigating Unit is gunning for companies that siphoned off R8.7 billion from Eskom after they were awarded irregular contracts over the past few years. SIU head Andy Mothibi told the Standing Committee on Public Accounts this week they had also identified a number of officials who had been doing business with the company and those who colluded with the private companies. He speaks to Jeremy Maggs on this. Courtesy #DStv403
