Former CEO of the Passenger Rail Agency of South Africa (Prasa) Lucky Montana will finally appear before the commission of inquiry into state capture in Johannesburg on Friday morning.

Montana has been implicated in wrongdoing by various witnesses who have appeared before the inquiry. He is accused of abusing his powers as CEO and giving tenders and contacts to friends and those loyal to him. Montana was head of Prasa between 2010 and 2015 until he was fired by the board amid the claims.

Montana is accused of collapsing corporate governance at Prasa.

He is also alleged to have inflated the value of the contract for front company Swifambo Rail from R3.5 to R5 billion. There are many other accusations levelled against the former CEO, which he is expected to explain to the commission.

In a statement last year, he accused the commission of being biased and said the inquiry was a witch hunt against him.

He has taken to Twitter to express his elation over the chance to tell his side of the story.
