Irish 1,000 Guineas heroine Lake Victoria has been ruled out of the Coronation Stakes at Royal Ascot.

Undefeated in five juvenile starts last season, including Group 1 wins in the Moyglare Stud Stakes, the Cheveley Park and at the Breeders’ Cup, Aidan O’Brien’s filly was beaten into sixth place in the 1000 Guineas at Newmarket on her return to action but bounced back to her best in the Irish equivalent.
