Pretoria - Suspended Special Director of Public Prosecutions Lawrence Mrwebi is expected to testify on Wednesday at the Mokgoro inquiry on the damning allegations made against him.
He is fighting off efforts to deem him unfit to hold office.
Mrwebi has been accused, among other allegations, of protecting former Crime Intelligence boss, Richard Mdluli from prosecution by withdrawing corruption charges he was facing.
Mdluli bought luxurious cars with a loan secured from Atlantis Nissan, the company supplied vehicles for Crime Intelligence.
Advocate Jan Ferreira previously testified that they had prima-facie evidence and were ready to go to trial when Mrwebi withdrew the charges with no valid reason.
