Four-time Group One winner Kingman's racing career is over and he has been retired to stud.
The highly rated three-year-old, trained by John Gosden, was one of the stars of the 2014 Flat racing season.
But treatment for a sore throat means he will miss his autumn targets and owner Prince Khalid Abdullah has decided to retire the colt.

|"Kingman ran for the same owner as Frankel, and although not quite as prolific as Flat racing's unbeaten champion of 2010-2012, he wasn't a million miles behind him.|
|"After suffering his only defeat when beaten narrowly in a vintage 2000 Guineas at Newmarket, the son of the stallion Invincible Spirit lived up to his Dad's name with a terrific run of Group One success, notably in the St James' Palace Stakes at Royal Ascot.|
|"Kingman's absence from British Champions Day at Ascot in October is a major blow to the fixture, though, to be fair, there should still be plenty of big names on show. He'll be being prepared to join Frankel and Oasis Dream at his owner's stud: what a breeding team they should make."|
Kingman won seven of his eight outings, including the Irish 2,000 Guineas and at Royal Ascot and Glorious Goodwood.
His only defeat was an unlucky second place in the 2,000 Guineas at Newmarket in May.
"He's certainly the best colt I've ever trained," said Gosden.
"He's a fabulous-looking horse with a great mind on him and he had this ability to change six gears at once.
"He had a turbo charge that no other horse I've trained has possessed."
The son of Group One winner Invincible Spirit, Kingman made his debut with a remarkable six-length win at Newmarket in June 2013.
Kingman's last race was the Prix Jacques le Marois in Deauville, in which he finished well clear of Anodin.
His retirement means a third meeting with Night of Thunder - the winner of the 2,000 Guineas - at October's Queen Elizabeth II Stakes will not now happen.
He retires having collected £970,834 in prize money and will take up a role at owner Khalid Abdullah's Banstead stud alongside the legendary Frankel, who ended his racing career in October 2012.
