A half-brother to Dubawi from the first crop of Frankel, UAE King is bred in the purple and the strapping bay with the distinctive white markings has shown a record of steady racecourse improvement, most notably when finishing runner-up at Lingfield last month.

The three-year-old bettered that form with a game display in sticky ground here, sitting second down the back straight before lengthening inside the final quarter mile to put sufficient daylight between himself and Godolphin newcomer Festival Of Ages, who loomed to challenge but could muster no more inside the final furlong.

The margin of victory was a length at the line, with the John Gosden-trained Joshua Reynolds staying on steadily for third.

Roger said: “UAE King continues to improve both mentally and physically and he should continue to progress across the course of the summer. He would be happier on better ground, but he has got the job done and he remains a nice prospect.”

Daira Prince also became a winner on his fourth start having landed the 1m2f handicap at Yarmouth two hours earlier.

A colt with another fine page, being a Dubawi half-brother to Group 1 winner Chinese White, Daira Prince formed part of a fabulous four-timer on the card for the in-form Silvestre De Sousa when holding off the fast-finishing Seafarer by a diminishing head.

Roger said: “Daira Prince has appreciated the step up in trip and he is another who ought to continue to go the right way. He won’t be unduly punished by the handicapper for this success and he should win more races this season.”
