London Security conference 2026 is a flagship initiative to be held at the National Liberal Club in London on September 7, 2026, bringing together policymakers, security experts, civil society leaders, academia, and youth voices from across Europe and its neighbourhood. The initiative organised by LI, EGI, ELF, and Radikale Venstre, responds to urgent security and resilience challenges in Europe’s most exposed regions – the Arctic, Ukraine, the Balkans, and the Caucasus/Black Sea – shaped by Russia’s aggression, China’s growing influence, hybrid threats, and democratic backsliding. It aims to develop actionable liberal policy recommendations to strengthen collective security, democratic resilience, and regional cooperation.
