Various members of the wannabe upper crust started fox hunting here in Northern California. It didn't last. The coyotes regarded it as a swell way to eat a dog and have fragrant tasty broken legged horse carcasses left in inaccessable spots. I think the solution is clear: import coyotes into the British Isles. This will solve your problems with excess sheep too. After all, you've already got coyotes in your urban areas.
