Proclamation was then sent to Royal "Ascot" for the Group Three Jersey Stakes over seven furlongs. Because of redevelopments at Ascot Racecourse, all the course's fixtures were moved in 2005, with the Royal meeting taking place at York. Ridden by Johnny Murtagh, he started the 7/1 third favourite behind the Michael Stoute-trained Home Affairs and the Sandy Lane Stakes winner Camacho. He was towards the rear of the field in the early stages and was hampered on the turn into the straight. When Murtagh switched him to the outside he made rapid progress, took the lead a furlong out, and won by two and a half lengths from Camacho. Following his win at York, Procalmation was transferred to the ownership of Sheikh Mohammed's wife Princess Haya of Jordan.
