England won the fourth and final Test against Pakistan by an innings and 225 runs at Lords here on Sunday and so took the series 3-1. But Pakistans heaviest Test defeat surpassing their innings and 198 runs loss to Australia in Sharjah in 2002 was overshadowed by allegations they had been involved in a betting scam. Britains News of the World newspaper claimed it gave 150,000 pounds (230,000 dollars, 185,000 euros) to a middle man in return for details about three no balls which later were bowled in the match exactly when he had predicted. The report alleged two Pakistan bowlers, Mohammad Aamer and Mohammad Asif, delivered the three blatant no-balls at points in the match agreed with the alleged fixer.
