Duduzane Zuma, son of former president Jacob Zuma, is now prepared to give evidence before the judicial commission of inquiry into state capture.

The head of the legal team, Advocate Paul Pretorius, told commission chair Deputy Chief Justice Raymond Zondo that he received a letter from Duduzane Zuma's legal representative over the weekend.

The letter confirmed that Zuma was ready to testify on a statement submitted to the commission by former deputy finance minister Mcebisi Jonas.

Jonas claimed the Guptas offered him R600m if he accepted the finance minister post. He also testified that Zuma drove him to the meeting with the Guptas, and that he was present during that meeting.

"It is good for the process of the commission that Mr Duduzane Zuma has made the decision that he will be prepared to give evidence and does tender to give evidence in this commission. That immediately places him in the same position as some of the applicants for leave to cross-examine," Zondo said.     

On Thursday, advocate Dawie Joubert told the commission that Duduzane Zuma was subjected to unlawful arrest when he arrived in South Africa, for his culpable homicide case involving an accident in 2014.

Joubert said at the time that "no South African should be subjected to unlawful arrest". Joubert also represents Ajay and Rajesh Gupta.
