Election-weary Britons head to the polls on June 8. The French will vote this weekend. Americans only recently concluded their distended democratic ritual. Different countries, different systems, different voters. A common theme? Immigration.

Donald Trump pulled off his unlikely victory by invoking a dichotomy: Americans versus others. The antediluvian promise to make America great again was pitched at a demoralised working class, deprived of a social safety net and denied real wage growth for decades.

It cleverly ignored the yawning gulf between a privileged, tax-astute billionaire and his new electoral quarry by excavating an even bigger hole in which immigration was conflated with national security, free trade with job losses, globalism with US decline.

In France, Marine Le Pen's far-right National Front exploits similar tensions by branding asylum seekers "illegal". "They have no reason to stay in France" Le Pen says blithely because "these people broke the law the minute they set foot on French soil".
