TOPSHOT - Former South African president Jacob Zuma arrives to appear before the Commission of Inquiry into State Capture on July 15, 2019 in Johannesburg, where he faces tough questioning over allegations that he oversaw systematic looting of state funds while in power. - Zuma struck a characteristically relaxed tone ahead of his televised appearance, which could last for five days, tweeting a video the day before of himself dancing and singing "Zuma must fall" before laughing heartily.
