Britain's biggest bookmakers Ladbrokes and William Hill have announced they're to refund thousands of pounds worth of bets placed on horses which have tested positive to performance-enhancing drugs.
The news relates to British racing's biggest doping scandal after 11 horses from the famous Godolphin stable owned by the ruler of Dubai, Sheikh Mohammed, tested positive for anabolic steroids.
The Sheikh's trainer Mahmood Al Zarooni could lose his licence after admitting to making a "catastrophic error" by administering the drugs, claiming he didn't know it was an offence to use drugs when the horses were not racing.
The episode is deeply embarrassing for the Sheikh, who has invested hundreds of millions of pounds in British racing over the last 20 years.
