The National Prosecuting Authority will call 50 witnesses to show that Glenn Agliotti and business tycoon Brett Kebble's partner John Stratton were involved in his assisted suicide, IOL reported on Monday.

According to the website, the NPA had officially recognised that the mining magnate orchestrated his own murder, quoting from a witness list it had obtained.

The murder trial has been moved to the Johannesburg High Court from the Regional Court.
