Daniel Trilling examines how ideas once relegated to fringe far‑right groups became respectable within British politics and media. Drawing on reporting and analysis, he traces the role of politicians, newspapers, think tanks and social media in mainstreaming xenophobic and nationalist rhetoric. The book situates these developments within broader political and economic shifts, including neoliberalism, austerity and the aftermath of the financial crisis. It explores how immigration became a central political fault line and how right‑wing populists capitalised on institutional failures. Trilling also considers what political courage and alternative programs might look like to resist further erosion of liberal democratic norms.
