Frankel’s full-brother had been expected to return to winning ways back over a mile and a quarter following his agonising defeat in the mile-and-a-half Grand Prix de Saint-Cloud.
Though James Doyle had to use energy to get Noble Mission across from his wide draw to take a prominent position in the early stages, all seemed well when he hit the front in the straight.
However, the Lady Cecil-trained five-year-old had no answer to the challenge by Ioritz Mendizabal on Lucky Lion, who got on top close home to take Group One the prize.
Victory for Andreas Lowe’s three-year-old paid a mighty compliment to Prix de l’Arc de Triomphe hope Sea The Moon, who thrashed him by 11 lengths in the Hamburg Classic.
Meanwhile, High Jinx secured a first Listed success of his career when he claimed the Prix du Carrousel at Maisons-Laffitte.
The James Fanshawe-trained stayer, second in the Henry II Stakes at Sandown on his last start in May, is a renowned mudlark and was sent off a well-backed favourite under Christophe Soumillon.
High Jinx eventually held off Trip To Rhodos by a head, with Biladi another length and three-quarters away in third.
