This is what Brexit has done to Britain. Luise Valentiner arrived in Scotland through Erasmus and made it her home for 32 years. She built a business, paid taxes and became part of her community. Before Brexit, 85% of her sales went to EU customers. Then came customs charges, returned parcels and regulations too costly for a sole trader to navigate. After three decades here, she was also forced repeatedly to prove her right to return to her own home. Add growing xenophobia and the rise of Reform, and she and her husband have finally had enough. They are leaving Scotland for Denmark. Luise has not fallen out of love with Scotland. Brexit has made living and belonging here economically, practically and emotionally exhausting. Britain is losing businesses, skills, friendships and people who enriched this country for decades. Brexit is national self-harm.
