Last year's runner-up Ambivalent is one of nine fillies and mares in the "Betfred £10 Million Scoop6 This Saturday" Middleton Stakes at York on Thursday.

Roger Varian's five-year-old, who won a Group One on the Curragh last year, was last seen arguably running a career-best in Dubai when third against the boys in the Sheema Classic.

Ralph Beckett's Secret Gesture was placed in three Group Ones last season after winning the Lingfield Oaks Trial and returns to action as a four-year-old.

Roger Charlton's Thistle Bird was only narrowly touched off in the Nassau Stakes at Goodwood last summer and she remains in training as a six-year-old.

Michael Stoute's Mango Diva was an improver last season, while the Karl Burke-trained Odeliz represents Yorkshire.
