Sheikh Mohammed's racing and endurance riding operations hit by fresh controversy In May, in an unrelated case, the VMD seized and destroyed steroids and anti-inflammatories among other unlicensed medications on a private plane at Stansted airport, half an hour's drive from Newmarket. Telegraph Sport has learned that the Royal College of Veterinary Surgeons, the practitioners" regulatory body, and VMD are liaising over the Stansted issue. Lizzie Lockett, RCVS spokesman, said: "If an unregistered vet, for example, an overseas vet, or other person has been involved, there could be a breach of the Veterinary Surgeons Act and we would support any police investigations." A VMD spokesman confirmed both raids were "intelligence-led" but said: "We cannot reveal any more detail because of ongoing investigations." Both the BHA and Darley have stated that Moorley has no racing or thoroughbred breeding use. The site is understood to be the UK base for Dubai-based endurance horses during the European summer season. A Darley spokesman said staff had been told not to discuss Moorley with the media and that a statement would be issued. When the Al Zarooni scandal broke, Telegraph sport revealed the professional connection between Al Zarooni and one of Sheikh Mohammed's principal endurance trainers in Dubai, Mubarak Bin Shafya, who has been described as a "repeat offender" by the International Equestrian Federation (FEI) Tribunal. Three Bin Shafya-trained horses that tested positive to the steroid stanozolol in 2010 and 2011 were suspended by the FEI "for their own welfare." Middle Eastern endurance, notably the United Arab Emirates, accounts for 40 per cent of FEI Tribunal doping cases, out of 120 other member nations. FEI president HRH Princess Haya, Sheikh Mohammed's wife, convened crisis talks in June and a five-member strategic group was appointed. But the Swiss and Dutch equestrian federations say the group, which includes Saeed Al Tayer, a senior figure in Dubai racing circles, is "not neutral," and demand it be chaired by someone outside equestrianism. "The independence of the group cannot be assured," said Charles Trolliet, president of the Swiss federation.
