A stable spokeswoman for Luca Cumani, Daliapour's trainer, reported: "He is in good form and as things stand, he is an intended runner. Gerald Mosse will ride." The going is also a worry for the Prix du Jockey-Club winner Montjeu.
Aidan O'Brien, the leading Irish trainer, has four - Tchaikovsky, Urban Ocean, Festival Hall and Genghis Khan - in the race. Dermot Weld's Derrinstown Stud Derby Trial victor Port Bayou and the Kevin Prendergast-trained Mudaa- Eb complete the line-up.
Henry Cecil, Oath's trainer, has reported his colt "fit and well". Willie Carson, racing manager to Oath's owners, said: "Oath is fine. We just want the rub of the green in Ireland."
With fine weather forecast the going at the Curragh - described as good - could dry out and the track may be watered later in the week.
Carson does not believe that will cause Oath problems. He said: "He wouldn't want extremes of going. He'll go on anything although perhaps not very soft. His form is on cut and he wouldn't want it too fast."
Coral report support for Oath for the King George & Queen Elizabeth Stakes. He is now 4-1 their favourite from 6-1.
