A flag flies at the Stanford cricket ground in Antigua February 13, 2009. Just three weeks ago, Allen Stanford was listed as one of the 100 most influential people in British sport. Now, the Texas billionaire is at the center of the latest investigation by Wall Street regulators. In recent years, the flamboyant 58-year-old financier and cricket mogul has seldom strayed far from controversy - from tangling with leaders of Antigua where he is the biggest single investor to ruffling the well-mannered world of international cricket by cavorting with the players' girlfriends.
