Delhi Games drug free - so far

New Delhi - The Commonwealth Games have been clean so far on one front: 500 athletes who have been tested for doping have all been given the all-clear.

Commonwealth Games Federation president Mike Fennell told a scheduled news conference Saturday that 1 500 doping tests were planned during the games period, "and that target remains." He said all tests conducted up to Thursday had come back negative, "and that is a positive result."

The federation is responsible for testing the athletes and the World Anti-Doping Authority is observing. Fennell said that the number of tests will increase in pace with the number of finals - under the testing regime, all medal winners are tested and some are done randomly.
