London Defence Conference 2026

Policy, Alliances, Europe’s defence The London Defence Conference 2026 takes place in April. Attendance is by invitation only. This is the fourth edition of the LDC – the geopolitical gathering for friendly countries drawing together leaders, policymakers, military, industry, academia and selected media – where the big questions on defence and security are addressed. As well as the keynotes and panels on our main stage, there is also huge demand for side sessions and closed session roundtables. In the evenings, our Chairman’s Dinner and our Director’s Dinner have become popular features of the LDC, although spaces are limited. At the heart of the London Defence Conference is our relationship with King’s College London and its world-leading School of Security Studies. The LDC is made possible with the backing of our headline sponsors and supporters. Plus, our partnership network hosts leading research institutions and international think tanks. And the LDC SME Network is a hub of innovative, fast growing startups and mid-tier companies.
