LONDON - In the stands and from afar, some of the biggest names in Britain were cheering on Andy Murray at Wimbledon. There was Alex Ferguson, the recently retired manager of Manchester United, sitting among the crowd at the All-England Club and smiling broadly. And there was David Cameron, the country's prime minister, tweeting his well-wishes before the match and then later a photo of him watching it on television.
