Sunday promises a packed schedule of top‑class racing across three venues – Brighton, Worcester and the famed French meeting at Deauville – all streamed live on Sky Sports Racing. The centerpiece of the French card is the Group One Sumbe Prix Jean et Louis Romanet, where the brilliant three‑year‑old filly Diamond Necklace will take the lead off the front‑stretch. Aidan O'Brien’s star juvenile has been unbeaten in six starts, including four victories at the highest level, and she most recently dominated the Nassau Stakes at Goodwood. She now faces older rivals in what many expect to be her seventh consecutive win.

Also featuring in the French feature is Joseph O'Brien’s filly Rebel Moon, ridden by Dylan Browne‑McMonagle. Rebel Moon impressed with a fourth‑place finish in the Irish Oaks and could be poised to improve on that effort in this Group One test. Christophe Ferland will have his own hope in Aventure, the 2023 Prix Vermeille champion.

Although she appeared slightly off‑form in a recent run behind Calandagan at Saint‑Cloud, her Group Two triumph in May suggests she still possesses the class to cause an upset. Red Letter, another strong contender, rounds out the top tier of the field.

Meanwhile, the Sumbe Prix Morny, a prestigious Group Two sprint, will see eight sprinters line up, including the promising Orthodox and the well‑handled Man’s Best Friend. Aidan O'Brien has entered three runners in the day’s program, with Man’s Best Friend being the one selected by Ryan Moore. The colt, after a modest fourth‑place debut, broke his maiden at Naas and then captured the Group Two Richmond Stakes at Goodwood, indicating he is ready to compete with the best.

Great Barrier Reef, who suffered a setback after his Coventry Stakes win at Royal Ascot, will be closely watched by punters looking for a bounce‑back performance. Orthodox, the Norfolk Stakes winner, is a fascinating prospect for trainer Clive Cox; the colt displayed a blistering turn of foot over five furlongs and should adapt comfortably to the six‑furlong distance of the Morny. Senorita Bonita, fresh from an impressive win over Libertango at Newmarket and a recent victory at York, will also be in the mix and deserves serious consideration.

Sky Sports Racing continues to deliver the latest racing news, in‑depth interviews and feature stories directly to mobile devices, ensuring fans stay connected to the sport they love. In addition to the French action, the Brighton Summer Series Final will culminate with the Blackmore Equestrian Construction Handicap at 3.50 pm, promising a fiercely contested finish. Mark Loughnane’s son Billy will ride Arnaz in the plate, a horse that has shown great enthusiasm after securing two wins at Chepstow.

Arnaz should remain a factor as the race heats up. Several other runners also present solid each‑way opportunities, notably Diomed Spirit and Big Time Rascal, both previous winners who could repeat their success. Top‑weight Prefer The Sister commands respect after leading the field in her last five starts, demonstrating consistency and stamina that could prove decisive. Further highlights from the Deauville meeting include the Group Two Prix du Calvados at 12.58, where Dee’s Funny Girl, trained by Donnacha O’Brien, will contest the race.

At 1.33, the Group Two Prix Kergorlay features the popular Santorini Star, with Joseph O’Brien also fielding a contender. Back in England, the Brighton track will host a Class Four race at 4.20, with Sea Suite heading the field. Overall, Sunday’s programme offers a blend of established champions and emerging talent across sprint and middle‑distance divisions, providing ample excitement for racing enthusiasts. Whether you are tracking the unbeaten Diamond Necklace in France or following the competitive handicaps at Brighton, Sky Sports Racing ensures you won’t miss a moment of the action.
