Wilton Park marks 80 years with shift to broader UK diplomatic role

Wilton Park has marked its 80th anniversary by setting out a renewed mission to act as the United Kingdom’s main multilateral facilitator, with a broader role supporting British diplomacy at a time of strain on established international systems.

The Foreign, Commonwealth and Development Office executive agency said the updated approach reflects changes in global power and growing pressure on traditional diplomatic forums. The strategy aims to widen how the UK engages internationally by placing greater weight on flexible formats and a wider range of participants.

Founded in 1946, Wilton Park has a long record of convening dialogue among policymakers, officials, civil society figures and business leaders. Its work has covered post-war reconstruction in Germany, transatlantic security, climate policy and global health cooperation.

Under the revised mission, Wilton Park plans to deepen engagement with partner countries while maintaining support for major multilateral institutions. It also plans to increase work through smaller groupings and informal settings, bringing together faith groups, civil society organisations and private sector figures alongside governments.

A new Global Impact Group has been formed to link senior business leaders with policymakers, with the aim of improving coordination and testing policy ideas. Wilton Park will also contribute to the recently established College of British Diplomacy, offering civil servants opportunities to develop professional skills and build international contacts.

Tom Cargill, chief executive of Wilton Park, said the UK required new methods to connect and exert influence during a period of international disruption. He said the organisation was expanding its role to convene a wider range of voices in areas where traditional state-led diplomacy faced constraints.

As part of the anniversary programme, Wilton Park plans to host a major dialogue in summer 2026 focused on the future of international diplomacy. The event is expected to examine current practice and set out proposals for new approaches to international engagement.

Baroness Gisela Stuart, chair of Wilton Park, said the organisation’s capacity to host trusted and discreet discussions remained central to British diplomatic efforts. She said the UK would continue to rely on Wilton Park as a diplomatic asset capable of bringing together a broad range of international perspectives.

Wilton Park was established on 12 January 1946 by Sir Heinz Koeppler to support education and democratic development among German prisoners of war. Based at Wiston House in West Sussex since 1951, it now hosts around 80 events each year, with more than 3,000 participants from over 100 countries.
