Truth, rumour, conspiracy? Gill Bennett OBE had the job of sorting fact from fiction as chief historian of the Foreign Office from 1995-2005, and senior editor of its official history of British foreign policy, Documents on British Policy Overseas. During over thirty years as a historian at Whitehall, she provided historical advice to twelve foreign secretaries under six prime ministers, from Edward Heath to Tony Blair. In this conversation with James, Gill takes us through the biggest conspiracies of the World Wars.
