Andrew Graham, co-founder of DHI Performance Horses, died suddenly on 1 July of a heart attack. He was 54.

Mr Graham set up his own livery and dealing yard when he was in his 20s, before establishing DHI Performance Horses with business partner Ian Woodhead in 1994.

Initially specialising in dressage, the company quickly became known for supplying top-quality sport horses across all disciplines. These include DHI Topper, winner of last week’s Olympic test event.

Mr Graham’s funeral was held on 13 July. He leaves wife Jo and children Katie and Kris.
