It was one of those rare, uplifting moments in politics — not mindless euphoria, but well-founded hope for a better future, based on solid evidence and achievement. It was, inauspiciously, Friday 13, but few people noticed on that December day in 2019, for the country had just emerged from a prolonged period of parliamentary anarchy, replaced by a Conservative majority of 80 seats, with all obstacles to “getting Brexit done” now removed. It was a moment of relief, of restored stability and of reassertion of the public will over entitled elites.

Yet it was much more even than that: it was a historic moment in British political culture, for the Conservative party had not just won a landslide majority, more significantly, it had done so by finally overcoming the hereditary prejudices of many thousands of working-class voters in neglected parts of the country and attracting their support.
