SA Communist Party leader Chris Hani's killer Clive Derby-Lewis' application for parole was postponed in the Pretoria High Court on Tuesday.

The matter was postponed to mid-November to allow other parties to be joined to the motion.

Derby-Lewis (72), who made a brief appearance in court, was convicted along with Janusz Walus for Hani's assassination on 10 April 1993.

Their sentences were commuted to life imprisonment in 1995.

Derby-Lewis' attorney, Marius Coertze, said the Hani family joined the motion on Monday afternoon.
