Frankel was at his majestic best as he made it a perfect 14 victories in the final race of his career, the Qipco Champion Stakes at Ascot.
The world's highest-rated racehorse, trained by Sir Henry Cecil, won his 10th Group One race with a trademark display of pure brilliance - despite a momentary scare when he was slowly away from the stalls.
Sent off the 2-11 favourite, Khalid Abdullah's wonder colt took up the running from Cirrus Des Aigles over a furlong out under his ever-present jockey Tom Queally and pulled away from the French star to win cosily by a length and three-quarters.
Cecil said: "He didn't like the crowd much, but he was very relaxed. He's the best I've ever had. He's the best I've ever seen. I'd be surprised if there's ever been any better."
Abdullah, one of the world's leading racehorse breeders, confirmed that Frankel has run his last race and is to be retired.
