At Sunday’s French Oaks at Chantilly, Aidan O’Brien’s Diamond Necklace, unbeaten in three starts, heads an 11‑horse Prix de Diane field. The two‑year‑old won the French 1000 Guineas and now faces a five‑furlong stretch that should play to her strengths. Her victory would double O’Brien’s Group One tally before the season climax arrives and fans await the result.

British runner Lilt, also unbeaten, rides under William Haggas and steps up markedly in class. Felicitas, after a first defeat against Legacy Link at York, keeps her reputation intact as Kieran Shoemark remains confident. Green Spirit tops the home side, while Evolutionist, a 1000 Guineas runner‑up, threatens Karl Burke in the same race for the.

Doncaster hosts the Yorkshire Air Ambulance EBF Fillies’ Novice Stakes, featuring Enchant, winner of a Pontefract debut, and Raneem, a pedigree contender. Four‑year‑old Shamalza, now under Ralph Beckett, adds intrigue. The field promises a tight contest as newcomers aim to upset seasoned rivals in a race that could reshape novice rankings for the season ahead.

Meanwhile, Chantilly’s Prix Bertrand du Breuil pits Sahlan, Group One Prix du Moulin winner, against Remmooz, a seasoned miler who finished third to Jonquil at Ascot. Matauri Bay and Elastic complete the quartet. With Sahlan rated the one to beat, the race could decide the top miler status in the summer classics for the season.
