I’ve been encouraged to do a post about Brexit Day, but I don’t have anything to say about it. The only sign of it that I have seen on the streets of London was a perfectly preserved bubble car driving down Pall Mall flying two ostentatious Union Jacks, which I took to be a perfect emblem of the public mood: a small minority with an entirely outdated and somehow diminished jingoism driving at high speed into irrelevance; but I am trying not to be pessimistic.
