A syndicate which owns Cheltenham Gold Cup favourite Kemboy has been barred from registering horses in Ireland.

Horse Racing Ireland has announced all registrations of horses under the ownership of Supreme Horse Racing Club have been voided following a persistent failure to provide requested information.

HRI said it had "consistently sought, and not received, the requested complete members' information for horses running under Supreme Horse Racing Club".

Entries for Supreme horses were suspended last month.

The syndicate will no longer be allowed to own or part-own horses registered under rules in Ireland.

"Despite repeated requests, Supreme Horse Racing Club has failed to provide the members' details required under Horse Racing Ireland Directive 15 Racehorse Ownership," the HRI statement said..

"Horse Racing Ireland is disappointed that it is necessary to take this step but due to the lack of engagement and failure to provide the necessary information there is no alternative but to withdraw approval of the club and to cancel its registrations as a recognised club."

HRI said it had met with Supreme's trustee in July after complaints from som member of the ownership group.

"At that meeting there was a commitment by Supreme Horse Racing Club to file the necessary paperwork with HRI," the governing body said.

HRI said there was repeated correspondence over the next three months which did not yirld the required response.

Jason Morris, director of racing for HRI, said it had received significant correspondence from concerned members.

He said HRI would share the information obtained about the club with the British Horse Racing Authority.

"HRI is open to accept the re-registration of these horses under accepted ownership structures. HRI cannot adjudicate as to the shareholding of these horses," he said.
