The International Research Journalism Consortium (ICIJ), which is made up of several media outlets, analysed over several months 356 gigabytes of data on Isabel dos Santos' business between 1980 and 2018, which help to rebuild the path that led the country's former president's daughter to become Africa's richest woman.
During the investigation more than 400 companies (and their subsidiaries) were identified to which Isabel dos Santos has been linked over the last three decades, including 155 Portuguese and 99 Angolan companies.
The information gathered details, for example, a cover-up scheme set up by Isabel dos Santos at the Angolan state oil company Sonangol, which allowed her to divert over 100 million dollars to Dubai.
They also reveal that, in less than 24 hours, Sonangol's account with Eurobic Lisboa, the bank of which Isabel dos Santos is the main shareholder, was emptied and left with a negative balance the day after the resignation of the businesswoman.
The data disclosed indicate four Portuguese people allegedly directly involved in the financial schemes: Paula Oliveira (non-executive director of Nos and director of an offshore company in Dubai), Mário Leite da Silva (CEO of Fidequity, a Lisbon-based company owned by Isabel dos Santos and her husband), the lawyer Jorge Brito Pereira and Sarju Raikundalia (Sonangol's financial director).
