London Defence Conference

What London Defence Conference does

The London Defence Conference (LDC) is an invitation-only annual geopolitical gathering founded in 2022 in response to Russia's full-scale invasion of Ukraine, organised under the UK private limited company Reaction Digital Media Ltd (Company number 10166531) with a 16-person team based at 71-75 Shelton Street, London. Its core product is a three-day annual conference held each spring at Bush House, King's College London, bringing together heads of state, prime ministers, defence secretaries, ministers, US Congress members, chiefs of defence, and senior industry figures from friendly and allied nations to discuss global security themes (Ukraine, NATO, AUKUS, Indo-Pacific, deterrence). The portfolio has expanded to include the LDC Washington Forum (annual autumn event with CSPC), the LDC Investment Forum (City of London event focused on European defence capital deployment), the LDC SME Network for innovative defence companies, and LDC Papers for research dissemination.

The business model is sponsorship-driven rather than ticket-driven: the LDC monetises through headline sponsor and supporter tiers sold to defence industry, defence technology, finance, and professional services firms (2026 headline sponsors include Palantir, Blackstone, Deltroit, Defense Technology Alliance, Exiger, Tiberius, and Santander, alongside approximately 20 supporters such as BAE Systems, AWS, Rolls Royce, MBDA, Serco, Shield AI, and Freshfields). Distribution is controlled through invitation-only accreditation, and credibility is reinforced by strategic partnerships with King's College London's School of Security Studies (academic partner and venue), Sky News (Official Media Partner), and a partnership network of more than 20 think tanks and research institutions including CEPA, RAND Europe, Hudson Institute, Council on Geostrategy, and CSPC.

Governance is led by Chairman Lord Salisbury and Director Iain Martin, with Commodore Neil Brown (Rtd), Professor John Gearson, Professor Niall Barr, and Hillary Briffa forming the organising committee alongside Head of Sponsorship and Partnerships Georgie Krone. The conference has run three editions to date (May 2023, May 2024, May 2025) with LDC 2026 scheduled as the fourth edition in April, alongside the now-annual LDC Washington Forum (23 September 2026) and LDC Investment Forum (early December 2026), indicating a deliberate multi-event, multi-geography productisation strategy rather than a one-off conference.

Expansion highlights5 records

Direct peers

• Center for Strategic and International Studies (CSIS): Major US bipartisan defense and foreign policy think tank that hosts high-profile defense events. Directly comparable as both a LDC partner (co-host of Washington Forum) and a competing convening platform for senior US defense officials and industry.
• Munich Security Conference (MSC): The leading global forum for heads of state, defense ministers and senior security officials, held annually in Munich. Directly comparable to LDC as an invitation-only defense and security gathering, but operating at a larger scale and with longer institutional history.
• IISS Shangri-La Dialogue: Asia's premier defense summit hosted by the International Institute for Strategic Studies. Comparable as a high-level defense policy conference for ministers, military chiefs and officials, but focused on the Indo-Pacific security architecture rather than the Euro-Atlantic agenda.
• Aspen Strategy Group: US-based convening body bringing together senior policymakers, business leaders and thought leaders on national security and foreign policy. Comparable to LDC as an invitation-only senior-level strategic dialogue forum, though focused on US policy elites.
• Reagan National Defense Forum: Annual defense conference hosted by the Ronald Reagan Presidential Foundation. Comparable as a senior-level gathering of US and allied defense policymakers, industry executives, and thought leaders, though US-centric in agenda and speakers.
• RUSI (Royal United Services Institute): UK's leading defense and security think tank, which hosts frequent defense conferences, briefings and lectures. Comparable to LDC as a UK-anchored convening body for defense policy dialogue, though with a broader research mandate and longer history.
• Halifax International Security Forum: Annual transatlantic defense and security conference held in Halifax, Nova Scotia. Comparable to LDC in inviting democratic-allied defense ministers, officials and industry leaders for off-the-record discussion, though longer-established and US-government-aligned.

Emerging players

• Council on Geostrategy: UK-based foreign policy and defense think tank that is also an LDC partner. Comparable as a convening and thought-leadership body on UK and allied defense policy, though smaller in scale and event portfolio than LDC.

Broad incumbents

• Chatham House (Royal Institute of International Affairs): UK-based international affairs think tank hosting major conferences on geopolitics, defense and security. Comparable to LDC in convening senior officials, diplomats and industry, though with a much broader global agenda and century-long institutional history.

Regional players

• Ditchley Foundation: UK-based foundation hosting high-level, off-the-record conferences on international security, defense and policy. Comparable to LDC in convening allied officials and experts at Chipping Norton and London venues, though more academically grounded and less defense-industry sponsored.
