Philip Robinson won the big race at Newmarket on board the 11-1 shot Rakti.
The horse refused to go in the stalls for the Emirates Airline Champion Stakes 12 months ago, but made amends in emphatic style when taking the £400,000 prize.
The four-year-old, trained by Michael Jarvis, set sail for home two furlongs out and quickly pulled clear of a quality field before finishing two lengths clear.
Daryll Holland rode a blinder to force Carnival Dancer up into second a length and a half ahead of Indian Creek. Favourites Alamshar, Russian Rhythm and Nayef were nowhere to be seen.
