Making extensive use of official material which has recently been released and which casts particular illumination on the rupture which the Suez crisis caused in Anglo-American relations, the author examines the long-term and short-term causes, the principal events from nationalization until the aborting of the military operation in November 1956, and the consequences of the crisis on the standing of Britain with the rest of the world. The full extent of the collusion that took place among the British, the French and the Israelis before the famous ultimatum was sent to Egypt is considered, as is the role in the crisis of Prime Minister Sir Anthony Eden.
