Former President Jacob Zuma's case of fraud and corruption at the KwaZulu-Natal High Court in Pietermaritzburg has been postponed to June 23 to allow for an investigation into his failure to appear in court in February, according to the National Prosecutor's Office.

Zuma and French arms company Thales are facing 16 charges, including racketeering, fraud, corruption and money laundering.

The case was to resume Wednesday.

The court issued an arrest warrant for the former president after he failed to appear in court in February.
