Former cabinet minister Malusi Gigaba is due to return to the Palm Ridge Magistrates’ Court on Friday morning, as prosecutors continue to pursue a corruption case connected to multimillion-rand locomotive deals at Transnet. The case is one of several linked to investigations into corruption at state-owned enterprises during the previous decade. While the other accused face a range of charges, Malusi Gigaba is charged with a single count of corruption. The allegation relates to conduct between November 2010 and May 2014, when he oversaw the public enterprises portfolio. The proceedings are being closely followed, as they are seen as a test of South Africa’s efforts to hold senior political figures accountable for corruption linked to state-owned companies.
