Four Irish among Duke Of Cambridge 17 There is a strong Irish posse among the 17 six-day acceptors for the Duke of Cambridge Stakes at Royal Ascot on Wednesday. Aidan O'Brien's French import Peace Burg could possibly be joined by Pearl Of Africa, Purr Along and Fiesolana. Andre Fabre's Esoterique has been supplemented for the Group Two contest over a mile. The four-year-old was narrowly beaten in the French 1000 Guineas last season and on her most recent outing she edged out Sir Michael Stoute's Integral in the Dahlia Stakes. There are a couple of other French possibles in Kenhope and L'Amour de Ma Vie. Integral is in the mix, as is Richard Hannon's Sky Lantern, who may drop in class having raced at the highest level exclusively ever since she was beaten by Hot Snap in the Nell Gwyn last April. Hannon can also call upon Zurigha. Godolphin's Certify, Charlie Hills' Irish Guineas heroine Just The Judge and Jonny Portman's Annecdote may also have a part to play.
