Paddington (GB) (Siyouni {Fr}) heads a field of four for the G1 Juddmonte International S. at York with Aidan O'Brien's star three-year-old bidding for a fifth success at the highest level.
His chief threat is Shadwell's G1 Prince Of Wales's S. hero Mostahdaf (Ire) (Frankel {GB}). The John and Thady Gosden-trained colt will be accompanied by stablemate Nashwa (GB) (Frankel {GB}), who bids to rebound off a third-placed effort in the G1 Nassau S at Goodwood.
King Power Racing's Derby fifth The Foxes (Ire) (Churchill {Ire}) will have his first start since last month's GI Belmont Derby Invitational in New York where he finished an unlucky second.
Opening day on the Knavesmire will also feature the five-runner Sky Bet G2 Great Voltigeur S., in which Wathnan Racing's undefeated G2 Queen's Vase victor Gregory (GB) (Golden Horn {GB}) will line out in advance of a possible tilt at next month's G1 St Leger.
The pattern-race action gets under way with the seven-furlong G3 Tattersalls Acomb S., which has attracted six juveniles headed by another Wathnan Racing acquisition, Ballymount Boy (Ire) (Camacho {GB}).
He was last seen finishing second to G1 Prix Morny hero Vandeek (GB) (Havana Grey {GB}) in this month's G2 Richmond S. at Goodwood. The Adrian Keatley trainee will exit from gate two for his first start in fresh silks.
