Pretoria - The establishment of an inquiry into National Prosecuting Authority boss Mxolisi Nxasana's fitness to hold office is at an advanced stage, the presidency said on Friday.

“Progress is also being made with regards to identifying persons who will constitute the inquiry at various levels, and also to conclude the terms of reference,” spokesman Mac Maharaj said in a statement.

“An announcement will be made as soon as the processes have been completed.”

President Jacob Zuma announced his decision to institute the inquiry on July 5, after reports emerged that Nxasana had apparently not been given a security clearance because of past brushes with the law.

This included being tried for murder about 30 years ago. He was acquitted on the charge based on his version of self-defence.
