A full bench of the Gauteng High Court in Johannesburg will hear President Cyril Ramaphosa's application for an interdict against his predecessor's private prosecution on Thursday.

Former president Jacob Zuma accuses Ramaphosa of "being [an] accessory after the fact to crimes committed by, among others, Adv Downer" and alleged breaches of the National Prosecuting Authority (NPA) Act.

Advocate Billy Downer is prosecuting Zuma on behalf of the State for arms deal-related corruption. Ramaphosa argues that Zuma's prosecution is being done with an ulterior motive as he was served with the summons the day before the ANC's national elective conference started.

Zuma has denied this.
