Chief Prosecutor Shaun Abrahams has confirmed that South Africa’s immediate past President, Jacob Zuma, is to face prosecution for 16 charges of corruption.
Mr Abrahams said he believed there were “reasonable prospects of a successful prosecution”.
The charges – which Mr Zuma denies – include counts of fraud, racketeering and money laundering.
Mr Zuma, 75, was forced to resign as president last month by his party, the ruling African National Congress (ANC).
He was facing his ninth no-confidence vote in parliament before he left office.
The charges relate to a 30bn rand ($2.5bn; £1.7bn) government arms deal in the late 1990s before he became president.
According to BBC, Mr. Zuma faces one charge of racketeering, two charges of corruption, one charge of money laundering and 12 of fraud.
Mr Zuma has always denied claims that he received bribes from bidders in the deal.
