The win was also a maiden top-flight success over ten furlongs for Sheikh Mohammed Obaid’s son of Dubawi, but he proved just as dominant dropped back in trip, dispatching a 12-strong field, which included four further Group 1 winners, with a performance steeped in class.

A two-length winner of the Dubai Sheema Classic in March, Postponed was last seen romping home in the Coronation Cup at Epsom in June.

He subsequently missed the opportunity to defend his King George VI & Queen Elizabeth Stakes crown at Ascot through a respiratory infection, but he proved fully recovered from that minor setback here, scooping a whisker short of £550,000 in a race that was deemed to be the best in the world by the international handicapping team last year.

Andrea Atzeni was once again masterful aboard Postponed, settling the five-year-old in third place as stable companion King Bolete cut out the running at the head of affairs.

As was the case at Epsom, Jack Mitchell was also seen to textbook effect aboard the pacemaker, setting beautifully-judged fractions as twelve lengths separated first and last passing through the first half-mile.

King Bolete completed his role inside the three-furlong marker as the increasing tempo became too much to handle. But looming menacingly on his outside was Postponed, the yellow and black-spotted silks of Andrea motionless as those in behind were asked to close the gap on the leader.

Try as they might, they found the margin remaining beyond their grasp, Andrea asking Postponed to win his race inside the two. He looked in little danger thereafter, with Postponed edging slightly towards the stands’ rail when the result was all but sewn up.

Highland Reel finished second, a length and a quarter adrift, with a further length back to Mutakayyef in third.

In securing the victory, Postponed increased his career earnings to over £4,360,000, closing the gap on the all-time record for a British-trained horse, while he continued another remarkable season for his super-stallion, Dubawi.

Roger said: "He's an incredible horse and I'm very lucky to train him. We didn't have long to get him ready and he only really turned the corner two weeks ago.

"In the last seven days he'd looked to have blossomed and the change in him over the last week gave us confidence he was right. I trusted in the horse's condition and he's delivered.

“Congratulations to Sheikh Mohammed Obaid and all of the team at home. This was a wonderful victory and I am delighted for everyone involved with the horse.

"The Prix de l'Arc de Triomphe is likely to be his next target."
