Gibraltar faces eight rivals Dual Guineas winner Rock Of Gibraltar heads a field of nine horses to stand their ground at the final 48-hour declaration stage for the £250,000 St James`s Palace Stakes at Royal Ascot on Tuesday. Aidan O`Brien`s ace, who landed the Sagitta 2000 Guineas at Newmarket before following up in the Entenmann`s-sponsored equivalent at Newmarket, is joined by stablemates Landseer and Sahara Desert. Johnny Murtagh has been booked for French 2000 Guineas hero Landseer with Michael Kinane expected to get the leg-up on Rock Of Gibraltar. King Of Happiness, who disappointed in the Newmarket Classic after wining the Craven Stakes, represents the Sir Michael Stoute stable. Pat Eddery replaces Kieren Fallon on the Spinning World colt. Andre Fabre`s Bowman (Frankie Dettori) and William Haggas` Dupont (Darryll Holland) both take their chance having been added to the field at a cost of £20,000. The field is completed by Clive Brittain`s Camp Commander, Mick Channon`s Aramram (Steve Drowne), and the Terry Mills-trained Where Or When (Jimmy Fortune).
