Nicola Wilding knew the letter was from her brother, Billy, as soon as she saw the line of tape on the envelope flap. His mail had to pass inspection: he was three months into a prison sentence for attempted carjacking with an imitation gun. “Have you spoken to Mum lately?” he wrote. “She’s turned into a fascist, lols.”
It was 2013 and their mother – a 59-year-old care worker, who for most of her life had voted Labour – had just attended her first march with the English Defence League. Wilding read her brother’s news while at the kitchen table in her flat in Glasgow. “Was I worried?” she says. “I was bemused. I thought: ‘Oh, Mum’s just being daft. She’s having an adventure. She’ll get over it.’” But instead, “the anger stayed”, more marches followed – and Wilding started to wonder what personal and political forces had led her family to this place.
