Drug test for all Olympic Brits

All of Britain's 900 Olympic and Paralympic athletes will be drug tested at least once ahead of the Games, it was announced today.

UK Anti-Doping revealed athletes will face no-advance-notice, out-of-competition blood and urine tests.

Chief executive Andy Parkinson said target testing will be based on "intelligence gathered from a wide range of sources."

He added: "The aim is to test every member of the British teams at least once. Those in more high-risk sports or disciplines, or athletes of interest to us will be tested more often.

"Essentially there is no limit to the number of times we might test any individual athlete."

Olympics Minister Hugh Robertson said: "Drug cheats have absolutely no place in sport. We want our athletes to be positive role models for the millions watching the Games this summer."
