As an American citizen, Meghan Markle may not be aware that, up and down the land, the British public is preparing to celebrate her wedding to Prince Harry on May 19 in its own special way. Or that (whisper it) not all of us are that interested in the actual event, but see it as a great excuse to close the road, get the bunting out and do what we do best: sit about on plastic chairs, feasting on Victoria sponge and warm prosecco while discussing the state of the nation, possibly under a light drizzle, and wearing a Union Jack apron.
