Geoff Huffer, trainer of dual 2000 Guineas winner Cockney Rebel, has decided to quit training for a second time.
Huffer, 60, first quit in 1991 after his backers were forced in to receivership but insists this time it is purely his decision.
"I have decided to give up training for good this time," he told the Racing Post.
"It has been at the back of my mind since Cockney Rebel went wrong in September, and it makes sense to go out now, at the top, rather than at the bottom.
"It has been an absolutely magnificent experience second time around, and Cockney Rebel has taken me to places we could only dream about.
"I would like to thank all of my owners, including Phil Cunningham, owner of Cockney Rebel, and Kevin Mercer of Usk Valley Stud for their support."
Huffer was a former drummer with 1970's band Mungo Jerry before taking up training between 1978 and 1991.
He enjoyed notable success with the likes of Tina's Pet, Ile De Nisky (fourth to Nashwan in 1989 Derby and third to Old Vic in Irish version), and St James's Palace Stakes winner Persian Heights.
He went in to the transport business after quitting first time but unfortunately spent five months in prison in 2001 for non-payment of duty. He began his second spell training in 2004 at Grange House Stables.
Huffer added: "I'll have a nice rest until after Christmas and have a holiday, which I haven't had for three years.
"I may still be involved with horses in future but I won't train again."
