Chatham House

Chatham House is an independent, non-governmental UK Foreign Policy institute based at 10 St James's Square, London, led by Director-General Bronwen Maddox since 2021. Roughly 300 staff and fellows work across programmes covering Russia and Eurasia, the Middle East and North Africa, the Americas, Asia-Pacific, Europe, and global economy and finance.

It is best known outside academic circles for the Chatham House Rule, devised in 1927, which lets officials and diplomats speak candidly at meetings without attribution, making the institute a preferred neutral venue for back-channel dialogue between adversarial governments. It publishes International Affairs, one of Britain's oldest peer-reviewed journals, alongside The World Today and regular policy briefs.

Unlike IISS, which specialises in quantitative military data, or RUSI, which focuses on defence operations, Chatham House sits where international law, diplomatic history and economic policy intersect. Its Russia and Eurasia programme is among the most influential Western academic voices on Kremlin decision-making, and its Middle East and North Africa programme, led by Sanam Vakil, provides much of the London-based analytical framing on Iran.
