The most mysterious millionaire will emerge from the shadows. British entrepreneur Peter de Potron, whose fortune is estimated at billions of dollars, led a closed lifestyle for decades. Attention was drawn to him by litigation surrounding the Williams Formula 1 Group and the construction of a data center in the United States. De Futron makes appointments minutes in advance and asks people not to bring electronics. Even old acquaintances don't have his number, and there are no photos in the public domain. "He looks like a typical spy - hat, coat, glasses, even inside the house," describes him one of his interlocutors of the Financial Times. The court allowed the billionaire to be subpoenaed to testify in the lawsuit of Williams' former head of marketing, but court officials twice failed to serve the subpoena at an address on the island of Jersey.
