Harbinger put up a devastating performance to run right away with the King George VI And Queen Elizabeth Stakes at Ascot.

Olivier Peslier looked to be going best as he sat in fourth place as they turned into the straight in the Group One contest, and the response was electrifying when he asked for an effort.

The Sir Michael Stoute-trained colt (4-1) brushed Derby winners Cape Blanco and Workforce aside as he powered an amazing 11 lengths clear, with Cape Blanco finishing second and Youmzain third.

Peslier said: "You can imagine how I felt in the last furlong when I saw the big screen and I could see the others so far behind.

"The horse today is the king, he is a wonderful horse. I knew he was very good, but today he was flying and won so well.

"He travelled the way I wanted and he kept going, I didn't have to ask him anything. He was just flying. He is a champion."

Stoute added: "Olivier was just cantering, he travelled so well and he was looking good from a long way out.

"He was a decent three-year-old and was impressive in winning the Gordon Stakes at Goodwood. Then he had a blip in the Voltigeur, but he bounced back well in the John Porter this season and has gone on from there. We'll consider the Arc."
