Duke looking to crowned prince

Duke Of Marmalade will face 12 rivals as he aims to land a third successive Group One victory in the Prince Of Wales’s Stakes at Royal Ascot on Wednesday.

Aidan O’Brien’s four-year-old, winner of the Prix Ganay and the Tattersalls Gold Cup this season, will clash with Sir Michael Stoute’s Ask, the Henry Cecil-trained Phoenix Tower and former St Leger winner Sixties Icon.
