Princess Haya of Jordan is in a sticky situation. As current president of the International Equestrian Federation (FEI), she’s undertaken a few controversial actions, including the recommendation, a few weeks after the Olympics, to disband the FEI’s dressage committee.

Now her husband, the ruler of Dubai, is in hot water. Two of the long-time endurance competitor’s horses tested positive for Guanabenz and 16-beta hydroxystanozolol after an investigation.

Although it’s unlikely Sheik Mohammed cares for his own horses, under FEI rules the rider, not the caretaker, is held accountable for their animals.

  Sheik Mohammed told the Associated Press that he was unaware of the drugs but accepts full responsibility.

Princess Haya, who has been a decisive advocate of drug-free equestrian sports during her FEI tenure, stepped aside while the FEI considers her husband’s case, the AP says. After the Olympics, when multiple horse/rider teams were disqualified for drug use, Haya set up a special committee to tackle the issue.

Sheik Mohammed sat out a race immediately after the findings came to light, imposing his own ban even though the FEI had not yet ordered it. He has promised to share the results of his private investigation into the matter.
