Across western democracies, established conservatives are yielding to radical nationalism. There’s no sign that Britain will be the exception

In free societies, when you don’t like the government, you support the opposition. In dictatorships, or under military occupation, you join the resistance. The distinction isn’t precise but it matters.

All European democracies have radical anti-immigration parties, some on the fringes of opposition, some that have crossed into the mainstream.
