Cirrus Des Aigles turned in a masterclass from the front to record a remarkable 12th win at Longchamp in the Prix d'Ispahan.

The Group One race was billed as virtually a match between Corine Barande-Barbe’s stable star and Olympic Glory, but Richard Hannon’s recent Lockinge Stakes winner could finish only fourth under Frankie Dettori.

Cirrus Des Aigles (3-5F), who had defeated Arc winner Treve on his last start, made almost every yard of the running in the hands of Christophe Soumillon in his 17th start at the Parisian track.

The eight-year-old was pressed by the revitalised Anodin, but Soumillon had far too much class beneath him and eased home inside the final 100 yards.

Pollyana finished third.

Olympic Glory, who seem unable to run to his form around a turn, was hard at work a couple of furlongs from home on his first try over nine furlongs and folded meekly late on.

Cirrus Des Aigles has now amassed almost €7million in prize money, more than any other horse in the history of European racing.

Earlier in the day, We Are stretched her unbeaten record to three races with victory in the Pour Moi Coolmore Prix Saint-Alary.

The Freddy Head-trained filly was a little reluctant to enter the stalls, but she showed a really sharp turn of foot once Thierry Jarnet's companion warmed to the challenge.

Lady Penko set a fair gallop in the esteemed Group One over a mile and a quarter, but she was brushed aside by the George Strawbridge-owned We Are at the three-furlong pole.

Vazira's chances were compromised by an awful start from stall six, and while she made encouraging late gains to take second place, the winner was still well on top at the line.

The Prix Vicomtesse Vigier saw Fly With Me get the verdict over the front-running Goldtara in  a head-bobbing finish to the Group Two stayers race over just shy of two miles.
