Sir Eric Parker, owner of 1991 Grand National hero Seagram, has died aged 81.
Parker, who had battled cancer in recent years, was a leading light in the Racehorse Owners Association during a 43-year involvement with the sport that also saw the likes of Topsham Bay and miler Indian Lodge race in his colours.
A statement from the ROA read: "We are deeply saddened to announce that Sir Eric Parker passed away in his sleep this morning.
"He had just returned from Deauville, where he had gained great pleasure seeing Crimbourne Stud sell its highest price yearling ever at public auction.
"Sir Eric had defied medical opinion for many years during a lengthy battle with various forms of cancer."
Rachel Hood, the ROA president, added: "Everybody at the ROA is devastated to learn of Sir Eric's passing.
"His personal bravery in his fight against illness has been an example to us all and, no matter how unwell he felt, it never diminished his drive and determination to improve the sport he cared so passionately about.
"His greatest love was for his wife, Marlene, and his family, and our hearts go out to them all at this incredibly sad time."
