The Ditchley Foundation is a British organisation based at Ditchley House near Chipping Norton, Oxfordshire, which aims to promote international relations, especially Anglo-American relations, through a programme of around fifteen annual conferences on matters of international interest. The foundation was incorporated in 1958 by Sir David Wills, descendant of the tobacco importing family, W. D. & H. O. Wills of Bristol.
At each conference, around forty invitees are drawn from senior levels of politics, business, the armed forces, media, and academia, with roughly a third of guests being American, a further third being British, with the remainder being of other nationalities. The director of the Foundation is usually a retired ambassador - the current director is Jeremy Greenstock, former British Ambassador to the United Nations.
Discussion begins with all members present, before participants divide into three sub-groups, each having its own chairman and rapporteur to summarise proceedings. Proceedings end with one more conference-wide session. Like the similar Bilderberg meetings, discussions are private and non-attributable.
A corresponding American Ditchley Foundation helps to shape the conference program as well as select American participants.
