Lope De Vega romped away with the Prix du Jockey Club (French Derby) at Chantilly to follow up his victory in the French 2000 Guineas.
Slipping his field early in the straight in the hands of Maxime Guyon, the Andre Fabre-trained colt quickly pulled several lengths clear.
None of his rivals got near enough to put in a challenge and he scored easily from Planteur.
The winner was the last of the 22 runners to enter the stalls but he was smartly away as Vive Libre set the pace for Planteur, the Elie Lellouche first string.
Ryan Moore, bidding to follow up his Epsom triumph on Workforce, had his mount Ice Blue handy while Brian Meehan's Dancing David and the Aidan O'Brien-trained pair of Viscount Nelson and Cape Blanco were also well placed.
However, it was a one-horse race once Lope de Vega hit the front as Vivre Libre had cried enough on the turn for home. Frankie Dettori was third on the Nicolas Clement-trained Pain Perdu.
