According to BBC, in the report, former Public Protector Thuli Madonsela recommends Mr Zuma establish a judicial commission of inquiry within 30 days.

Zuma is accused of an improper relationship with wealthy businessmen.

He had tried to block the release of the report, but dropped his court bid on Wednesday. BBC reports.

The president and leader of the governing African National Congress (ANC) has been pressed by corruption allegations for more than a decade, but has repeatedly denied any misconduct.

Police fired water cannon to disperse protesters who marched on Mr Zuma's main office in Pretoria to demand his resignation.

According to information by BBC the 355-page report by former anti-corruption chief Thuli Madonsela is entitled "State of Capture" and is illustrated on its front page with a hand strung with puppet wires.

Deputy Finance Minister Mcebisi Jonas is quoted in the report as saying that businessman Ajay Gupta offered him 600m rand ($44.6m) last year, "to be deposited in an account of his choice", if he accepted the post of finance minister.

Mr Gupta also asked him if he had "a bag which he could use to receive and carry 600,000 rand in cash immediately," Mr Jonas alleged, adding that Mr Zuma's son, Duduzane, was present at the meeting.

He was expected to remove key Treasury officials from their posts and advance the Gupta family's "business ambitions", Mr Jonas is quoted as saying.

The businessman has not yet commented on the report, but has previously denied any wrongdoing.

The Gupta family is close to President Zuma, and the two have been nicknamed by the opposition as the "Zuptas".

After Mr Jonas rejected the alleged offer, little-known ANC MP Des van Rooyen was appointed finance minister.

Ms Madonsela said she had obtained evidence, including telephone records, placing Mr Van Rooyen at the Gupta's family home on seven occasions, including the day before the appointment.

Mr Zuma was forced to sack him four days later after South Africa's currency went into a tailspin.
