The letter was initiated by Dr Glen O'Hara of Oxford Brookes University and Dr Simon Szreter of St John's College, Cambridge, co-founder of History & Policy, an independent initiative working for better public policy through an understanding of history.
The initiative was founded by historians at the Universities of Cambridge and London and is based in the Centre for Contemporary British History at the Institute of Historical Research, University of London.
History & Policy's current work is funded with charitable grants from Arcadia and The Esmée Fairbairn Foundation.
