Irish racehorse trainers and breeders fear a Brexit that impedes the free movement of animals could threaten its success on the track and position as Europe's largest producer of thoroughbreds. Ireland is widely considered the European Union member most at risk from next door Britain's exit from the bloc, potentially cutting its land route to mainland Europe for exports and hindering trade with its key UK market. Few sectors are as integrated as the two islands' racing and breeding industries that, according to Horse Racing Ireland, the national authority for thoroughbred racing, contribute over 1 billion euros a year to Ireland's 189-billion-euro economy. "Our fears are that if there any trade barriers or any tax or tariffs on movement of horses between Ireland and England, that could have a detrimental effect," said Henry Beeby, chief Executive of Goffs, Ireland's leading bloodstock sales company.
