Oxfordshire | Deep in the salubrious agrarian dreamscape of the Cotswolds, on a narrow country lane, sits an unobtrusive stone shack. It may be buried in the heart of middle England, but it would be intimately familiar to millions of people worldwide who have never been anywhere near it.

The building, with its wood-beamed outhouse and its rutted parking lot for about 40 cars, is the shopfront of Diddly Squat – the made-for-TV farming venture of former Top Gear host Jeremy Clarkson.
