Donald Trump is being pulled along by three Mexicans. A throng of burning crosses carve a path through the night. Flaming torch bearers chanting strange incantations pass by too close for comfort. Is this a scene from The Wicker Man? Have I stumbled onto a movie set or perhaps I’m simply hallucinating.  Such thoughts are not out of place, because this is the annual Lewes Bonfire Night Parade, it is very real and I am right in the middle of it.
