Sunday promises a packed racing schedule, with live coverage from Brighton, Worcester, and the French venue of Deauville on Sky Sports Racing. The centerpiece of the day will be the Group One Sumbe Prix Jean et Louis Romanet, where the brilliant three‑year‑old filly Diamond Necklace will lead a high‑class field. Diamond Necklace, trained by the legendary Aidan O'Brien, has been unstoppable this season, having won all six of her starts, four of which came at the elite Group One level. After a commanding victory in the Nassau Stakes at Goodwood last month, she steps back up to face older horses once more.
Fans and pundits alike expect her to extend her unbeaten run to seven consecutive wins, further cementing her status as the season’s standout performer. Another intriguing contender is Rebel Moon, ridden by Dylan Browne‑McMonagle for Joseph O'Brien. The filly impressed when she finished fourth in the Irish Oaks and may yet prove that she belongs among the very best.
Her recent form suggests she could deliver a strong performance, especially if she finds the right pace. Aventure, the winner of last year’s Prix Vermeille, will be the primary threat for Christophe Ferland. Although she appeared a touch off‑colour behind Calandagan at Saint‑Cloud, her Group Two triumph in May indicates she possesses the class to challenge for the prize.
If she recaptures her best form, she could pose a serious challenge to Diamond Necklace. Red Letter is also in the mix, considered the best of the remaining runners and worth keeping an eye on as the race unfolds. The day will also feature a thrilling renewal of the Sumbe Prix Morny, a sprint contest that brings together eight promising juveniles, including Orthodox and Man’s Best Friend.
Aidan O'Brien will have three entries in this race, with Man’s Best Friend being the most highly regarded, especially after a strong ride from Ryan Moore. The colt, who finished fourth on his debut, then claimed a maiden at Naas before taking the Group Two Richmond Stakes at Goodwood, shows plenty of potential for further improvement. Great Barrier Reef, who suffered a setback after his Coventry Stakes win at Royal Ascot, will be a horse to watch in the betting markets, as connections assess his recovery and future prospects. Orthodox, the Norfolk Stakes champion, is a fascinating prospect for trainer Clive Cox.
The colt displayed a blistering turn of foot over five furlongs and should handle the step up to six furlongs without difficulty, making him a strong candidate in the Morny. Senorita Bonita, who out‑performed Libertango at Newmarket in her most recent outing, adds another layer of intrigue, especially after a successful run at York earlier this week. Her recent form suggests she could be a serious contender. In the Brighton Summer Series Final, the Blackmore Equestrian Construction Handicap will take place at 3:50 pm, offering a fiercely competitive showdown.
Arnaz, representing Mark Loughnane and ridden by his son Billy, arrives in high spirits after two wins at Chepstow and is expected to be a key player in this warmer‑weather contest. Other horses with each‑way chances include former winners Diomed Spirit and Big Time Rascal, both of whom have shown the ability to perform under pressure. Top‑weight Prefer The Sister also commands respect, having been placed first or second in each of her last five starts, indicating consistent high‑level performance.
