Tiger Roll’s winning connections after his Grand National victory, including Michael O’Leary, Gordon Elliott and Davy Russell Image supplied by The Jockey Club

All-powerful Gigginstown House Stud is to wind down its operations, Eddie O’Leary has announced.

The shock announcement indicated that scaling-back will begin with immediate effect, as O’Leary announced the operation will not be restocking at the store sales.

Speaking on behalf of his brother Michael O’Leary, Eddie O’Leary was reported by the Racing Post to have said: “Michael’s children are now growing with their activities, leaving less and less time for racing last season and for the foreseeable future.

“We’ve just had our best season ever in terms of winners and it’s been an amazing year capped by Tiger Roll winning the Grand National for the second time last month. 

“We have lots of young stock to be allocated among our trainers over the coming weeks and each of our trainers will receive their usual allocation of young point-to-pointers.”

Trainer Gordon Elliott, who has saddled many of Gigginstown’s biggest winners, including dual Grand National winner Tiger Roll and Cheltenham Gold Cup hero Don Cossack, is sure to feel the loss of horses keenly, having inherited many after their 2016 split with Willie Mullins.

Henry de Bromhead, Noel Meade and Joseph O’Brien are the other Gigginstown trainers, with Pat Doyle and Mouse Morris handling the point-to-pointers.

Morris had trained War Of Attrition to win the 2006 Cheltenham Gold Cup, one of the eary big successes for the operation.

Micheal O’Leary added: “We wish to sincerely thank all our trainers and their teams for the enormous success we’ve enjoyed over the past decade, but as my children are growing into teenagers I’m spending more and more of my time at their activities and I have less and less time for National Hunt racing, a situation that will continue for the foreseeable future.

“I hope that by running down our string over an extended four-or-five-year period it will give our trainers ample time to replace our horses without disruption.”
