Almost a millennium ago, Alan Rufus, a Breton warlord, helped his kinsman William the Conqueror squish a Saxon rebellion, pillaging and slaughtering across northern England. Today the view from his ruined castle in Richmond is serene, sheep gambolling beside the River Swale as it meanders through North Yorkshire. Richmond is “a lovely, historic, thriving market town”, effuses Colin Grant, a champion of local regeneration projects, as he shows off its 18th-century theatre.

Since 2015 Richmond’s MP has been Rishi Sunak, the (probably outgoing) Conservative prime minister. The constituency is a landscape of dry stone walls, the blissful Yorkshire Dales, idyllic villages and pubs named after farm animals. To be sure, the locals have grievances, including over agricultural policy and rural transport. “If you look under the surface, life has become harder,” insists Daniel Callaghan, the Liberal Democrat candidate in the general election on July 4th. But there is very little deprivation or crime. There are hardly any immigrants. What would a pensioner, relaxing in Richmond’s cobbled marketplace, like to change? “Nothing, really.”
