Mngoma, the estranged wife of former minister Malusi Gigaba, made her second appearance before Deputy Chief Justice Raymond Zondo. About an hour before she was due to finish her evidence, Zondo called for a 5-minute adjournment. Soon after, he said the commission had to close for the day because of security reasons. Mngoma is expected back at the commission this morning. Gigaba is also scheduled to give testimony.
