Top American runner Unbridled Command could make his British debut at Royal Ascot.

The four-year-old won the Grade One Hollywood Derby for trainer Thomas Bush last November and also claimed third in the Gulfstream Park Turf Handicap at the Florida track in February.

Subsequently transferred to the care of Ed Dunlop, the grey son of Master Command is entered in both the 10-furlong Prince of Wales's Stakes and the 12-furlong Hardwicke Stakes, although Dunlop has yet to make any definite plans.

"He's been with me for a little while now and we are starting to get to know each other properly," he said.

"He could start off at Royal Ascot, that's an option. He's entered in two races there but we've yet to decide on a plan."

Dunlop is targeting the Coronation Cup on Saturday week with Joshua Tree after his comeback effort in the Yorkshire Cup last Friday.
