Aliko Dangote, chairman of the Dangote Group, has alleged that Farouk Ahmed, chief executive officer (CEO) of the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA), spent about $5 million on the secondary school education of his children in Switzerland.

Dangote made the allegation in a paid newspaper advertisement published on Tuesday, claiming that the amount was spent on the education of four of Ahmed’s children over a six-year period.

The billionaire businessman had earlier, on Monday, accused Ahmed of paying $5 million to Swiss secondary schools for his children’s education, an action he described as economic sabotage and corruption.

In the advertisement, Dangote provided further details, listing the children as Faisal Farouk, Farouk Jr., Ashraf Farouk, and Farhana Farouk.

He also named the schools allegedly attended by the children during the six-year period as Montreux School, Aiglon College, Institut Le Rosey, and La Garenne International School.
