Opposition MPs will be looking for answers when the NPA appears before the justice committee.

CAPE TOWN - National Prosecuting Authority (NPA) boss Shaun Abrahams is expected to face questions about the decision to charge Finance Minister Pravin Gordhan in Parliament today.

The NPA is set to brief the justice committee on its annual report this afternoon a day after Abraham's announcement that Gordhan and two former South African Revenue Service (Sars) officials were being charged with alleged fraud.

Opposition Members of Parliament will be looking for answers when the NPA appears before the justice committee.

They are likely to want to hear from Abrahams why he chose to proceed with charges against Finance Minister Pravin Gordhan and why now.

Gordhan is set to deliver the Medium Term Budget Policy Statement in a joint sitting of Parliament on 26 October, just two weeks away.

Gordhan and former Sars officials Ivan Pillay and Oupa Magashula are set to appear in the Pretoria regional court on 2 November.

GORDHAN GOING NOWHERE

As Gordhan's lawyers say the fraud charge against him defies all logic, he says he will stay on to do his job as President Jacob Zuma again affirms his faith in him while big business, parts of civil society and sections of the African National Congress (ANC) are showing their support for him.

Gordhan has said the charges are politically motivated but that he will subject himself to the legitimate processes of the law.

His attorney Tebogo Malatjie says they simply don't understand how this charge could have been brought against their client.

"It defies all logic for us on what basis the minister could possibly have been guilty of fraud, given the facts that are in the public domain relating to all the matters that the Hawks could have been investigating."

But yesterday Abrahams said he had to bring this charge, as no one was above the law and he denied any claims of a political motive.

He says this charge simply relates to the way Pillay's pension was arranged.
