The first race of the 2025 meeting’s second day was overshadowed by the death of Harry’s Girl.
Harry’s Girl, trained by Richard Hannon, was pulled up with a serious leg injury by jockey Sean Levey during the Queen Mary Stakes.
The filly broke down midway through the five-furlong sprint for two-year-old horses.
“Unfortunately, Harry’s Girl suffered a fatal injury during the Queen Mary Stakes,” a statement said.
“Our thoughts go out to all connections at this time.”
Harry’s Girl, ridden by Sean Levey, was running in her third race, having previously finished first and second.
The race was won by 9-4 favourite True Love, under Ryan Moore for trainer Aidan O’Brien, from 100-1 shot Flowerhead.
Meanwhile My Cloud, the 3-1 favourite ridden by Silvestre de Sousa for trainer Roger Varian, was the shortest-priced winner in the history of the Royal Hunt Cup.
Irish trainer Paddy Twomey celebrated his first Royal Ascot winner as unbeaten Carmers won the Queen’s Vase for a third success on the trot.
Victory completed a rare treble for jockey Billy Lee, who had also secured victories at Cheltenham and Aintree within the last seven months.
