Coronation Stakes, Group 1, one mile (1600m), 3.45pm (BST)
The impressive QIPCO 1,000 Guineas heroine Homecoming Queen faces 11 rival fillies in Friday’s Group 1 contest.
The Aidan O’Brien-trained three-year-old, who was last seen finishing fourth behind Samitar in the Irish Guineas, is likely to be the trainer’s only representative, as Maybe has suffered a stone-bruise.
Samitar reopposes for Mick Channon and is once again ridden by young jockey Martin Harley. Channon also has a strong second-string to his bow in the shape of Laugh Out Loud, who has progressed through the spring and ran out an easy winner of a Group 2 in France last time out.
She will be ridden by Frankie Dettori while Mickael Barzalona gets the leg up on the Mahmood Al Zarooni-trained Irish History, who was supplemented for the race by owners Godolphin.
John Gosden appears to have a strong hand in this division and he runs three. Elusive Kate makes her anticipated return to action having won the Prix Marcel Boussac last term and Olivier Peslier takes the mount.
Stable jockey William Buick has somewhat surprisingly stayed loyal to Fallen For You, who was only sixth in a Lingfield Group 3 behind Chachamaidee, while Starscope, placed in the 1000 Guineas, will once again be ridden by Jimmy Fortune.
William Haggas runs the once-raced Cardigan with Chris Wall's Intense Pink, the Sir Michael Stoute-trained Russelliana and the sole French challenger Bugie D'Amore completing the line up.
King Edward VII Stakes, Group 2, 1m4f (2400m), 3.05pm.
Frankel's full-brother Noble Mission features among a field of seven declared runners in the King Edward VII Stakes.
An encouraging second on his sole juvenile appearance at Yarmouth, the three-year-old made a winning return at Newbury before following up in a Listed heat at Newmarket.
He suffered a narrow defeat at the hands of Thought Worthy on his latest appearance and tackles that opponent again this week.
Noble Mission is one of two runners in the mile-and-a-half test for trainer Sir Henry Cecil, with Thomas Chippendale stepping up in grade following an impressive handicap win at Newmarket.
John Gosden runs Investec Derby fourth Thought Worthy, as well as Shantaram, who ran some fine races in defeat before getting off the mark at Headquarters last time.
Aidan O'Brien runs Derby third Astrology, with Farhaan and Initiator completing the line-up.
Remainder of the card
The opening Group 3 Albany Stakes at 2.30pm has attracted 19 juvenile fillies, including Newfangled, a very impressive winner for the in-form John Gosden on her only start earlier this month.
The other Group 3 race is the Queen’s Vase, run over two miles (3200m) at 5pm, and Athens, who was placed at this level last time, could be a leading player.
Valencha has been promoted into the starting line-up for the Buckingham Palace Stakes over seven furlongs (1400m) at 5.35pm. The Hughie Morrison-trained five-year-old had been first reserve for the seven-furlong handicap, but gets the chance to shine following the withdrawal of Excellent Guest. Tariq Too could put his young trainer Amy Weaver on the map with a fine run here.
The Wolferton Listed Handicap, run over 10 furlongs (2000m) at 4.25pm, has attracted 16 runners, including the American raider Hyper, who comes here on the back for five straight wins.
