Aidan O'Brien fields Happily in the bet365 Fillies' Mile at Newmarket on Friday as he hunts down a 24th top-level success of the year.
The Ballydoyle handler is on the cusp of breaking Bobby Frankel's record of 25 Group-Grade 1 victories, and Happily will have the chance to add to her Moyglare and Prix Jean-Luc Lagardere wins as she spearheads a three-pronged O'Brien assault.
O'Brien also runs Magical and September, who finished second and third respectively in the Moyglare last month.
Karl Burke has declared May Hill winner Laurens and Ellthea, who claimed a handicap at Doncaster before successfully stepping up to Group 3 level in Ireland last time.
Charlie Appleby takes a steep rise in class with Newmarket maiden winner Magic Lily, while Mark Johnston's Nyaleti contests another Pattern event after a busy season.
Freddy Head provides an extra French dimension as he sends across Efaadah, who was a winner on her debut at Deauville but then had to settle for second in a Group 3 at Chantilly.
The Peter Chapple-Hyam-trained Lubinka, Eddie Lynam's Muirin, Paul Cole's Musical Art and Quivery, who represents Jeremy Noseda, complete the 12-strong line-up.
