Former president Jacob Zuma's legal team has told the Zondo Commission of Inquiry into State Capture that he will be withdrawing from the commission.

Zuma’s lawyer Advocate Muzi Sikhakhane said they are at the commission to say that they will take "no further part" in the proceedings.

Sikhakhane said he spoke with evidence leader Paul Pretorius on the phone on Thursday and will refer to a letter that stating Zuma's position.

He said a "crisis has been created here" because of not really knowing what rules the evidence leaders are following.

In the letter, the commission's lawyers set out their powers and point out that witnesses are not allowed to refuse to answer questions except on specific grounds in the Commission's Act.

The commission's legal team said they will "not make any concessions" in this regard and denied that Zuma was being cross-examined.
