Vandeek maintained his unbeaten record in brilliant fashion to edge out home favourite

Ramatuelle in a high-class renewal of the Sumbe Prix Morny.

Simon and Ed Crisford’s youngster arrived in Deauville with a perfect record, having followed up a Nottingham maiden success by claiming the Richmond Stakes at the Qatar Goodwood Festival, and he showed all his quality in this step up to Group One level.

Always travelling comfortably in the hands of Andrea Atzeni as Clive Cox’s Jasour set the pace, Vandeek followed the move made by Aurelien Lemaitre on Ramatuelle as the final furlong approached.

The duo soon became embroiled in a thrilling duel for the first prize, with Vandeek gradually finding himself alongside the stylish French runner and then ahead in the shadow of the post to strike a telling blow for owners KHK Racing Ltd.

The son of Havana Grey, who was a 625,000 guineas breeze-up buy in the spring, could now go in search of further Group One glory with both Paddy Power and Betfair going 7-2 from 11-2 for the Middle Park Stakes, 6-1 from 12s for the Dewhurst and 16-1 from 33s to taste Classic success next season in the 2000 Guineas.
