Conor Murphy, who landed £1m when a £50 accumulator

comprising five of his employer Nicky Henderson's horses came in at Cheltenham in March, has left the Lambourn trainer.

Corkman Murphy is to return to Kentucky, having spent time Stateside in between two spells with Henderson. The 28-year-old will set up on his own near Louisville, where he will break and pre-train with a view to acquiring a licence.

"Ideally, I would love to train in Ireland or England," he said, "but the prize money is not good enough, so I am going to America, where I worked for three years and have lots of friends and contacts.

"I was going to do this anyway, but obviously my win will mean that my first year over there will not be the struggle to keep my head above water that I had expected it to be."
