Ann Potts, who owned Cheltenham Gold Cup winner
Sizing John with her husband Alan, has died after a long illness.
The Potts' enjoyed an incredible season last year as along with Sizing John, Supasundae won the Coral Cup while Fox Norton, Sizing Codelco and Pingshou won at the
Grand National meeting.

The couple originally enjoyed great success through the Henry de Bromhead-trained Sizing Europe, among others, before splitting their horses up among several trainers in Ireland and sending Colin Tizzard a sizeable string in England.
Jessica Harrington, who trains Sizing John, told the Irish Field: "Ann was a lovely person. She was very brave and took great pleasure from Sizing John's win in the Gold Cup."
