This lovely illustration (by Luca D’Urbino) tops a terrific Leader in this week’s Economist:

BRITONS PRIDE themselves on their “unwritten” constitution. America, France and Germany need rules to be set down in black and white. In the Mother of Parliaments democracy has blossomed for over 300 years without coups, revolution or civil war, Irish independence aside.

Thanks to its stability, Britain convinced the world that its style of government was built on solid foundations laid down over centuries of commonsense adaptation.

That view is out of date. The remorseless logic of Brexit has shoved a stick of constitutional dynamite beneath the United Kingdom—and, given the difficulty of constitutional reform in a country at loggerheads, there is little that can be done to defuse it. The chances are high that Britons will soon discover that the constitution they counted on to be adaptable and robust can in fact amplify chaos, division and the threat to the union…
