Isabel dos Santos, Angola`s First Billionaire

Forbes Isabel dos Santos, the oldest daughter of Angola's longtime president, Jose Eduardo dos Santos, debuts on the Forbes list of the World's Billionaires with a fortune estimated at a minimum of $2 billion. She is Angola's first billionaire and the richest woman in Africa. Her first business, opened in 1997 when she was 24, was a restaurant called Miami Beach in Luanda, the Angolan capital. Though her representatives deny that her holdings have any connection with her father, research in Angola shows that President dos Santos has transferred stakes in several companies to his daughter. Her most valuable asset -- worth a conservative $1 billion -- is a 25% stake in Unitel, one of Angola's two mobile phone networks, where Isabel dos Santos is a board member. She also sits on the board of Angola's Banco BIC, where she also has a 25% stake. In Portugal, she owns nearly 15% of ZON Multimedia, a listed cable TV company, and just under 20% of Banco BPI, one of Portugal's largest publicly traded banks.
