On 23 June 2016, the British voter changed. Before that day, they picked a party, usually red or blue. By that morning, only two tribes mattered: remain or leave. And they kept mattering long, long after the result was declared. Rather than bin those short-lived and now stale allegiances, voters made them their personas. No longer a “Labour man” or a “Conservative family”, they became instead “remoaners” or “Brexiters”. Even today, 60% of Britons still identify themselves by where they scrawled a single cross in a one-off poll 10 years ago.
Ask about the difference Brexit has made and the answer normally concerns policy or high politics: how our economic trajectory has become bumpier, or how the Tories keep getting into punch-ups with each other. But it became so much bigger than Boris v Dave. The civil war blazed through the country, and recruited nearly all of us to one side or the other. The effects still ripple through our elections and media today.
