FORMER South African president Jacob Zuma will face prosecution on corruption charges is a stunning court decision.

“After consideration of the matter there are reasonable prospects of a successful prosecution of Mr Zuma,” said National Director of Public Prosecutions Shaun Abrahams at a media briefing in Pretoria, South Africa.

“A trial court would be the most appropriate (venue) for the ventilation of the issues,” he said

Mr Zuma has been charged over a $US2.5 billion ($3 billion) state arms deal.

The former president could now appeal the ruling on a number of grounds and argue that the decision is illegitimate as Mr Abrahams’ own position is uncertain.

Zuma, who was forced to resign by the ruling African National Congress last month, was at the centre of the deal to buy European military kit that has cast a shadow over politics in Africa’s most industrialised economy for years. Chief state prosecutor Shaun Abrahams told a media conference on Friday that Zuma’s attempts to head off the charges that have been hanging over him for more than a decade had failed.

The 75-year-old disputed all the allegations against him, he added. “After consideration of the matter, I am of the view that there are reasonable prospects of successful prosecution of Mr Zuma on the charges listed in the indictment,” Abrahams said.

“I am of the view that a trial court would be the most appropriate forum for these issues to be ventilated and to be decided upon,” he said. Zuma will face 16 charges relating to 783 instances of alleged wrongdoing, National Prosecuting Authority spokesman Luvuyo Mfaku said.

Then deputy president, Mr Zuma was linked to the arms deal through Schabir Shaikh, his former financial adviser who was jailed for corruption.

The counts were filed but then dropped by the NPA shortly before Mr Zuma successfully ran for president in 2009.

Since his election, his opponents have fought a lengthy legal battle to have the charges reinstated.

Mr Zuma countered with his own legal challenges.

Mr Zuma has also been implicated by South Africa’s anti-corruption watchdog in a 2016 report that alleges the Gupta family, billionaire friends of Mr Zuma, used links with him to win state contracts.

The Guptas and Zuma have denied any wrongdoing.

In addition to the corruption scandals that dogged his time in office, Mr Zuma was under fire for his handling of the economy, which has been battered by falling economic growth and record unemployment.

The opposition Democratic Alliance Party has campaigned since 2009 to reactivate the charges relating to the military contracts.

His successor President Cyril Ramaphosa has vowed to tackle corruption, admitting it was a major problem in the government.
