DA leader Mmusi Maimane has implicated the son of President Cyril Ramaphosa in questionable financial dealings with controversial government service provider BOSASA‚ alleging that Andile Ramaphosa received a suspicious R500‚000 payment from the company.

Maimane dropped the bombshell in the National Assembly on Tuesday when Ramaphosa appeared in the house to take oral questions from MPs - a session that started with the president taking questions on the VBS financial scandal.

Maimane used his chance to ask a follow-up question to raise the matter of Andile Ramaphosa and his dealings with BOSASA‚ a facilities management firm that has been at the centre of controversial government tenders involving several departments‚ politicians and other connected figures.

Maimane confronted Ramaphosa with papers showing how money was allegedly moved from a BOSASA business account to a trust account allegedly for the benefit of his son under dodgy circumstances.

"Now Mr President‚ here‚ I hold a proof of payment that was transferred to say‚ half a million rand needs to be transferred to a trust account called ‘EFG2’ on October 18 last year.

"This was allegedly put for your son Andile Ramaphosa. Following on to that‚ Mr President‚ I have a sworn affidavit from Peet Venter‚ stating that he was asked by the CEO of BOSASA that he must make this transfer for Andile Ramaphosa.
