Ante-post favourite Idaho heads a final field of nine that will contest this year's Ladbrokes St Leger at Doncaster on Saturday.
The son of Galileo is one of three runners from the yard of Aidan O'Brien, alongside Housesofparliament and Sword Fighter in the final British Classic of the season.
After finishing third in the Derby at Epsom and second in the Irish equivalent Idaho warmed up for the extended mile-and-three-quarter contest with victory last time out in the Great Voltigeur at York.
Heading the list of British challengers is the John Gosden-trained Muntahaa, who landed a Listed handicap at Chester on his most recent outing in what was just his fifth career start.
Ventura Storm, from the yard of Richard Hannon, will be looking to complete a hat-trick of wins having won a Listed contest at Hamilton on his penultimate start before taking Group Three honours in France last time out.
The field is completed by Harbour Law (Laura Mongan), Harrison (Mick Channon), Ormito (Andrew Balding) and The Tartan Spartan (Pat Shanahan).
