City firm Orchard has appointed former London Stock Exchange (LSE) chief executive Gavin Casey in a bid to help the firm pursue its ambition to become an international law firm. Casey, who will act as special counsel to the partnership on a part-time basis, was credited with transforming the LSE from a mutual society to a public limited company. "The job at Orchard represents an exciting opportunity to help with the growth of the firm, both in the UK and internationally," said Casey. Orchard is currently a 12-partner, full-service firm. But despite its small size, the firm has had international connections for some time. Property partner Roger Coral said: "Weve always had strong links with US firms, and were looking to put more effort into that."
