How a far-Right conspiracy infiltrated British politics - The Telegraph

Theory Briefing

• The Great Replacement Theory, rooted in anti-Semitic ideology, now shapes rhetoric in Britain's new populist wave.
• The theory's core claim — that Jewish influence is deliberately eroding white European identity — was once confined to far-right extremism.
• Its mainstreaming raises the question of whether populist movements are adopting the idea knowingly or absorbing it through laundered, softened versions.
• The Telegraph traces a direct line from fringe conspiracy origins to recognisable political talking points in British public life.
