"Ideally we would like this cleared up before April and that could yet happen," he said. "There has been a lot of publicity, but even now we still have no real idea about what this investigation relates to."
Meanwhile, wet weather could rob punters of the chance to see a vintage crop of Irish hurdlers in the AIG Europe Champion Hurdle on Sunday. Solerina is bound for the Leopardstown feature but Harchibald, Hardy Eustace and Accordion Etoile could all defect if the forecast proves accurate.
Harchibald headed a list of 35 entries for Cheltenham's Smurfit Champion Hurdle today. Jonjo O'Neill's Lingo was the only notable absentee, while Baracouda is 7-4 favourite for the Ladbrokes World Hurdle after it was confirmed that last year's winner Iris's Gift has not been entered.
Latest Champion Hurdle betting (William Hill): 3 Harchibald, 6 Back in Front, 8 Hardy Eustace, Macs Joy, 9 Accordion Etoile, 10 bar.
