TWICKENHAM, England – Britain's sports minister warns that doping poses the biggest threat to the integrity of the London Olympics.
Hugh Robertson says spectators must be able to trust that what they are seeing next year is a "fair contest." If they don't, he adds, the "integrity of the games will be lost."
Officials expect to conduct 5,000 doping tests at the London Games, compared with 4,500 at the 2008 Beijing Olympics.
