Classic hero Poetic Flare and the unbeaten Mostahdaf are among 13 colts declared for the St James’s Palace Stakes at Royal Ascot

Jim Bolger’s Poetic Flare landed the 2000 Guineas at Newmarket in early May, since when he has finished sixth in the French Guineas and runner-up in the Irish Guineas behind stablemate Mac Swiney.

Mostahdaf has won each of his three starts to date for John and Thady Gosden – completing his hat-trick in the Heron Stakes at Sandown almost four weeks ago.

The Frankel colt beat Charlie Appleby’s Highland Avenue by half a length in that Listed contest and the pair will renew rivalry at Group One level on Tuesday.

Appleby also saddles Irish Guineas sixth La Barrosa, while Jessica Harrington’s Lucky Vega also brings strong Classic form to the table, having finished third at Newmarket and fourth at the Curragh.

With William Buick siding with Highland Avenue, James Doyle is looking forward to partnering La Barrosa in a race which forms part of the Qipco British Champions Series.

He said: “He ran very well in the Craven when second to Master Of The Seas and then went for the Irish Guineas on what was obviously quite testing ground. He travelled into the race really well there, but didn’t quite see it out.

“I think he’ll be seen to much better effect on quicker ground at Ascot, and on his Craven run he’s entitled to go well in what’s obviously a tough race.”

Aidan O’Brien runs Battleground, Ontario and Wembley, with son Joseph represented by Thunder Moon.

Battleground and Wembley, who both sport first-time tongue ties, plus Thunder Moon all disappointed in the Guineas at Newmarket and Wembley has also since failed to fire in the Irish equivalent.

Bullace (Ralph Beckett), Chindit (Richard Hannon), Maximal (Sir Michael Stoute) and Naamoos (Mark Johnston) complete the line-up.
