I give you this screen-grab without comment. Maybe just in case I get libelled. But this story might help.
Incidentally, I was at Cardiff Central station one late Friday night, and literally walked past David Davis, looking very regal with just one aide of some sort, patiently waiting for something or other. No other security detail, as far as I could see. I said good luck to him, and thereby gave him the kiss of death. Cunning, that.
