Somerby's Gemini Stud celebrate as Classic Opera makes the grade Classic Opera made the grade as a Sport Horse GB Graded Stallions

The judges included Chris Hunnable and Jennie Loriston-Clarke MBE. Sport Horse GB Studbook is the largest studbook for Show Horses in Great Britain and has Her Majesty The Queen as a patron.

Other notable stallions who appear in their Studbook include last year’s Badminton winner Chilli Morning, and Jumbo who has sired two winners at the elite three-day eventing championships.

Classic Opera was the youngest stallion to be put forward for grading on the day and will be four later this month.

Steve and Georgie Revell were delighted at the grading result and will display Classic Opera in stallion parades at several three-day events this year.
