Many powerful, rich people seem to get away with corruption. But, the game appears to be up for Isabel dos Santos, Africa's richest woman. The daughter of former Angolan president José Eduardo dos Santos built a massive business empire on the back of political connections and access to deals involving state entities, like Angolan oil giant Sonangol. The 46-year-old woman is accused of stealing millions from state companies. Angolan authorities want to put her behind bars for charges that include money laundering, influence peddling and forgery of documents, says the AFP news agency – all charges strenuously denied by Dos Santos. Investigative journalists have also been unpicking Dos Santos's trail of wealth. The heat has been too much for at least one of Dos Santos's alleged accomplices, a banker who has been found dead. The case raises hopes that people like the Gupta brothers, who were behind wide-spread state capture in South Africa, and their friends will also be brought to book. – Jackie Cameron
