LONDON (AFP) - Prime Minister David Cameron on Saturday urged the whole nation to be proud of its "world beaters" after England became the world's number one Test side with a crushing victory against India. Cameron said he had watched the final overs of the match at Edgbaston, in which England beat India by an innings and 242 runs, from his sofa at home and would remember the experience for a long time to come. "I congratulate the England team on their fantastic achievement," Cameron said. "Their performance in this test, including England's highest ever innings score in a non-timeless test, and Alastair Cook's magnificent 294, against the team that has up to now been ranked number one in the world, is a tribute to their domination of the sport. "It was a massive team effort, bowling India out twice for less than 250. "I watched the closing overs on the sofa at home and will remember the joy of the crowd at Edgbaston and England getting to number one in such style for a long time to come.
