As a founding member of GLG Partners, Pierre LaGrange was for many years the posterchild of London's hedgefund scene. But then he decided to change tack dramatically, becoming CEO of Savile Row tailors Huntsman as the recession took hold. Today, Pierre tells us how a chance encounter in Ibiza changed the course of his life, how love at first sight in business is never a good thing, and why the American Ralph Lauren is the world’s best British brand.
