CLARIFICATION: This story has been edited to clarify the initial story published.

CAPE TOWN - President Cyril Ramaphosa has revealed that a half a million rand was paid to an account meant to fund his African National Congress presidential campaign by a company that also holds multi-million rand tenders with government for security services.

Bosasa, now known as African Global Operations, has also been linked to dodgy payments and security services for MPs.

However, Ramaphosa says he was unaware of any such payment until recently.

The president sent a letter to the Speaker of Parliament following a question in the house by official opposition leader Mmusi Maimane.

He asked about Ramaphosa’s son Andile’s dealings with the company.

The president told the National Assembly he believed his son’s business dealings and payments from Bosasa were above board.

In a correction issued on Friday afternoon, Ramaphosa says he has since found out that the company made a separate donation to a trust meant to fund his presidential campaign.

The president's son owns a financial consultancy that does work for Bosasa.

In the statement, Ramaphosa says since his response to the House, he's sought more clarification on the matter.

He says his son offers his services to African Global Operations in a number of African countries, but not South Africa, to avoid a conflict of interest.

Ramaphosa says he's been subsequently informed that the R500,000 payment was not for consultancy services, but rather a donation made by Bosasa CEO Gavin Watson into a trust account, used to raise funds for his ANC presidential campaign.

Ramaphosa now says the donation was made without his knowledge, and he didn't know about its existence on the day he answered questions in the National Assembly.
