QUIET Reflection gave North Yorkshire trainer Karl Burke his first Group One winner in Britain and former jump jockey Dougie Costello his maiden Group One winner on the Flat at Royal Ascot yesterday.

The filly had justified favouritism to win the Commonwealth Cup by a length ahead of rivals Kachy and Washington DC.

For Burke, who was banned from racing seven years ago, the success completed a remarkable return to the top.

Found guilty of passing information to former owner Miles Rodgers, the Middleham-based trainer had been stripped of his licence for 12 months in 2009 by the British Horseracing Authority.

Since returning to the game, he has enjoyed Group One success in both France and Italy with Lord Shanakill and Odeliz but, until now, not in his home country.

He said: "We had a few problems a few years ago but that's in the past. I know what happened there. I broke the rule and got punished for it.

"I think we have done well to get back where we are so quickly. This is fantastic. I can't have any complaints. I have had a great career."

Meanwhile Costello, who lives in Malton, was fighting back tears as the Ascot crowd cheered him and his ride into the winner's enclosure.

He said: "I owe Karl Burke a lot. Anybody would have won on her today and the last day. You want every ride to be like that.

"She really picked up on the ground and her courage has taken her all the way as well as her class."

Although Quiet Reflection has been entered for the July Cup at Newmarket, Burke admitted that she may now be rested until September at Haydock.

Queen Kindly, trained in Malton by Richard Fahey, yesterday became the first progeny of equine superstar Frankel to run at Royal Ascot but finished third in the Albany Stakes behind winner Brave Anna and second-placed Bletchley.
