South Africa’s top court gave the country’s former president, Jacob Zuma, a verbal tongue-lashing on Tuesday for his defiance of the law and ordered him to report to police within five days to serve a 15-month prison sentence for contempt of court. In a judgement delivered at the Constitutional Court in Johannesburg, Justice Sisi Khampepe, the acting deputy chief justice, accused Zuma of “outlandish” behaviour when he refused to obey a court order to appear before a commission of inquiry into high-level government and private sector corruption.
