Aidan O'Brien is set to rely upon Highland Reel in the King George VI And Queen Elizabeth Stakes at Ascot on Saturday. He will renew rivalry with the colt how beat him in the Hardwicke Stakes at Royal Ascot - Queen Elizabeth's Dartmouth who had been supplemented. Postponed remains the odds-on favourite to add to his two Group 1 wins so far this season.

Aidan O'Brien's Galileo colt, whose biggest successes have arrived on foreign soil in the Secretariat Stakes at Arlington Park and the Hong Kong Vase at Sha Tin, was narrowly denied by Darmouth in the Hardwicke Stakes at Royal Ascot last month where Seamie Heffernan suffered some interferance.
