The four-year-old chestnut soon had Blissful Moment in his sight and quickened two and a quarter lengths clear.

Averroes was third, while Rock A Doodle Doo completed the minor placings.

Johnston and De Sousa were also successful with Namibian in Friday’s Queen’s Vase.

Johnston said: ``It was a long week up until Friday, but it's fantastic to get two winners.

“This has been a difficult horse and he’s had a few changes of headgear.

“A few times he has really disappointed us, and he was in the sales at one stage, but he’s getting better and better.

“He looked a lot better today and he looked as though he’d even come on since Epsom.

“I’m not surprised he’s won – although I’m surprised he managed to overcome that wide draw.

“Silvestre said he was never where he wanted to be but at the same time the horse was always travelling very well for him.”

De Sousa added: “The horse travelled like a dream.

“I was happy with where I was but, at the same time, I was giving away a lot of ground.

“But the horse battled well and he was the best horse in the race.

“It’s unbelievable to rider winners here. When you look at my background, you would never think I would rider a winner in Royal Ascot.

“I got my licence over here just to have a spin and see how it went, but the way it is going is unbelievable.”
