President Cyril Ramaphosa will on Wednesday and Thursday appear before the state capture inquiry.
He will first give evidence in his capacity as the current ANC president and former deputy president of the party.
Afterwards, he will testify in his capacity as the current president and former deputy president of the country.
During his last appearance in May, the president admitted that corruption has negatively affected service delivery.
He also spoke on the step-aside rule, saying it was a fair and common practice.
The inquiry is attempting to determine how widespread state capture was in the country. It placed Ramaphosa’s predecessor, Jacob Zuma, and his associates, the Guptas, at the center of a corruption network across several state-owned enterprises.
While he previously testified on the ANC’s deployment policy, the Bosasa donations and the governing party’s relationship with corrupt members, he now has the task of explaining his own role in government at the time.
