Frankie Dettori, one of the outstanding jockeys of his generation, failed a drugs test when riding at Longchamp in France in September, his lawyer announced on Tuesday. The legendary Italian rider’s positive result will be the subject of a hearing conducted by France Galop, French racing’s governing body, in Paris next week. UK-based Dettori’s solicitor, Christopher Stewart-Moore, in a statement to the British Press Association, reported: “On behalf of Frankie Dettori I can confirm that, as a consequence of a positive test at Longchamp on September 16, 2012, he will be the subject of an inquiry by the Medical Committee of France Galop [the French horse racing authority] next week. “In compliance with, and out of respect for, the regulations of France Galop, he will not be commenting further until the France Galop procedures have been completed.”
