Full brothers Highland Reel and Idaho head 10 declarations for Friday's Investec Coronation Cup at Epsom.

The pair, who are both trained by Aidan O'Brien, are separated by just a year and though four-year-old Idaho achieved a career highlight when winning the Great Voltigeur last term, five-year-old Highland Reel boasts four Group 1 successes including last year's King George and Breeders' Cup Turf. O'Brien also fields US Army Ranger.

Godolphin have strength in numbers, too, as Charlie Appleby is responsible for 2016 Eclipse hero Hawkbill and Frontiersman, with Saeed bin Suroor set to rely upon Prize Money.

Journey makes her seasonal bow for John Gosden, while the Ralph Beckett-trained Air Pilot, Ed Dunlop's Red Verdon and Andrew Balding's Elbereth complete the line-up for the 12-furlong prize.
