EWN reports that Cosatu said on Monday it was concerned at the time it was taking the Special Investigating Unit (SIU) to begin its probe into government's spending on President Jacob Zuma's Nkandla home in circumstances where there was clearly prima facie evidence of wrongdoing. The SIU confirmed it had not yet started its probe, despite Public Works Minister Thulas Nxesi saying in January that he would ask it to investigate what he said was money spent only on security upgrades. Cosatu’s Patrick Craven said that, given the clear evidence that there was something wrong which the minister had made absolutely clear, Zuma has no choice but to issue a proclamation mandating the investigation.
