Heritage. It’s what Britain does best. We are famous for it. Brand Britain and heritage are synonymous. Stately homes; crumpets and honey; cricket on the village green. This surely is what brings tourists to our shores every summer, especially Americans, many of whom seem to regret that their forebears chose an independent path, depriving later generations of castles and royalty of their own. And it’s not that we are mercenary, but those dollars and the boost they bring to the economy certainly don’t go astray.
