Suez Crisis Protocol of Sèvres (October 22–24, 1956)
Introduction
In late October 1956, British, French, and Israeli representatives gathered at a villa in Sèvres, outside Paris, for three days of secret meetings. What emerged from those meetings was a written protocol — signed by the principals — that set out a predetermined scenario for the military seizure of the Suez Canal from Egypt. For decades, British officials denied that any such collusion had occurred. The documentary evidence proving it existed has now been public for nearly thirty years.
The Background: Nasser and the Canal
In July 1956, Egyptian President Gamal Abdel Nasser nationalised the Suez Canal Company, which had been jointly owned by British and French shareholders. The move was legal under Egyptian law but represented a profound political humiliation for Britain and France, which had treated the Canal as a vital imperial artery. Israel had its own grievances: Nasser had closed the Straits of Tiran to Israeli shipping and was supporting Palestinian fedayeen raids.
British Prime Minister Anthony Eden became consumed with removing Nasser, comparing him to Hitler in private correspondence. France, simultaneously fighting an Algerian insurgency it attributed partly to Egyptian support, was equally motivated. The stage was set for a conspiracy that would involve the highest levels of three governments.
The Sèvres Meetings
The key participants at Sèvres included, on the British side, Foreign Secretary Selwyn Lloyd (later replaced by Patrick Dean, a Foreign Office official); on the French side, Prime Minister Guy Mollet and Foreign Minister Christian Pineau; and on the Israeli side, Prime Minister David Ben-Gurion, Defence Minister Shimon Peres, and Chief of Staff Moshe Dayan.
The protocol they agreed was a staged performance. Israel would attack Egypt on 29 October 1956. Britain and France would then issue an ultimatum to both Israel and Egypt to withdraw from the Canal Zone. Egypt, being asked to withdraw from its own territory to a line 16 kilometres east of the Canal, would inevitably reject this. Britain and France would then launch their own military intervention, ostensibly to "separate the combatants" and protect the Canal — while in reality executing a pre-planned military operation to reassert control over it.
The document was signed. Eden, reportedly deeply uncomfortable with the written record of collusion, ordered the British copy destroyed. He later denied in the House of Commons that any foreknowledge of Israeli military action existed — a statement that was flatly false.
The Operation and Its Collapse
Israel invaded Sinai on 29 October as agreed. Britain and France issued the planned ultimatum on 30 October. Egypt rejected it. Anglo-French bombing of Egyptian airfields began on 31 October; a parachute drop on Port Said followed on 5 November.
The operation collapsed almost immediately under international pressure. US President Dwight Eisenhower, furious at not having been informed and alarmed at Soviet threats to intervene, applied decisive economic pressure on Britain — threatening to withhold IMF support for the pound at a moment of currency crisis. The UN General Assembly passed Resolution 1001 demanding a ceasefire. British and French forces withdrew by December 1956. Eden resigned on 9 January 1957, citing ill health, in what was universally understood as a political resignation.
Declassification and Historical Confirmation
The British government maintained official denial of collusion for decades. The Israeli copy of the Protocol of Sèvres was declassified by the Israeli State Archives in 1996 and subsequently published and analysed by historian Avi Shlaim in his 2000 work The Iron Wall: Israel and the Arab World. French copies were also found in French archives. The protocol is now a primary source document in Cold War history.
The Suez collusion is taught as established fact in British, French, and Israeli history curricula. Eden's Commons statements are recorded instances of a serving British Prime Minister lying to Parliament about an act of war.
What Would Change Our Verdict
Nothing would change the verdict — the documentation is complete. The Protocol is a primary source; the historiography is settled.

This act of document destruction was itself later confirmed by participants and in subsequent UK archival releases. It constitutes evidence of consciousness of wrongdoing and deliberate concealment.
Eden lied to the House of Commons about foreknowledge
SupportingStrongOn 20 December 1956, Eden stated in the House of Commons that Her Majesty's Government had no prior knowledge of Israeli military intentions. This statement was false. It is now a documented case of a serving British Prime Minister lying to Parliament about an act of war.
Selwyn Lloyd and Patrick Dean confirmed participation in memoirs and testimony

Eisenhower economic pressure forced withdrawal — confirming the operation failed politically
SupportingThe United States' application of decisive economic pressure on Britain — threatening to withhold IMF support for the pound — caused the collapse of the operation. Eisenhower's public anger confirmed that the US had not been told of the collusion, providing independent corroboration that the operation was conceived in secret.

SupportingEden resigned as Prime Minister on 9 January 1957, citing ill health, in what was universally understood as a political resignation forced by the Suez disaster. His departure confirmed the political scale of the failure and indirectly confirmed the magnitude of the deception involved.
Sèvres Collusion Was Openly Documented in Israeli and French Historiography by the 1980s
DebunkingThe Sèvres Protocol's existence was disclosed by Israeli historian Mordechai Bar-On and confirmed through French archives well before the 1990s British document releases. Moshe Dayan's memoirs and Shimon Peres's accounts referenced the tripartite planning, and Christian Pineau spoke publicly about it in France. The 'secret' framing substantially overstates how long the collusion remained concealed. By the time British documents were officially released, the core facts were already established in the historical record.
Eden's Destruction of the British Copy Was a Discretionary Political Act, Not Coordinated Cover-Up
NeutralAnthony Eden's order to destroy the British copy of the Sèvres Protocol reflected personal political shame and the conventions of British cabinet secrecy — not a coordinated multinational suppression effort. France and Israel retained their records, and the protocol was reconstructed from those sources. Eden's destruction eliminated one copy but did not prevent historical recovery. The asymmetry — two parties preserved records, one destroyed them — demonstrates the limits of the 'cover-up' framing as a coordinated operation.

Timeline
Nasser nationalises the Suez Canal Company
Egyptian President Gamal Abdel Nasser announces the nationalisation of the Suez Canal Company. British Prime Minister Eden reacts with fury, initiating secret planning for military action to reverse the nationalisation and remove Nasser from power.
Protocol of Sèvres signed by UK, France, and Israel
After three days of secret negotiations at a villa outside Paris, representatives of Britain, France, and Israel sign the Protocol of Sèvres. The agreement sets a predetermined military scenario: Israel attacks on 29 October; UK/France issue a staged ultimatum; Anglo-French forces "intervene" after Egypt's inevitable rejection.
UN ceasefire; Eisenhower economic pressure forces Anglo-French withdrawal
Under intense US economic pressure — Eisenhower threatening to withhold IMF support for the pound during a currency crisis — and UN General Assembly resolution, Britain and France agree to a ceasefire. Anglo-French forces withdraw by December 1956. The collusion is exposed internationally though official British denial continues.
Israeli Protocol of Sèvres declassified; Avi Shlaim publishes analysis
The Israeli State Archives declassify the Israeli copy of the Protocol of Sèvres. Historian Avi Shlaim publishes a detailed analysis in The Iron Wall (2000). The collusion, denied by British governments for 40 years, is now confirmed primary-source history.

Verdict
The Protocol of Sèvres is a confirmed primary-source document, declassified from Israeli archives in 1996 and published by Avi Shlaim (2000). It establishes that Britain, France, and Israel secretly agreed a staged military scenario to seize the Suez Canal. Eden destroyed the British copy and lied to Parliament. The collusion is settled historiography.
Frequently Asked Questions
Is the Suez collusion still disputed?
No. The Protocol of Sèvres is a declassified primary source document, confirmed by multiple independent archival collections — Israeli, French, and British. British participants subsequently confirmed their involvement in memoirs and testimony. Eden's lie to the House of Commons is documented. The collusion is settled historiography, not a conspiracy claim.
Why did Eden destroy the British copy of the Protocol?
Eden ordered the British copy destroyed because the written record of the secret collusion — if discovered — would confirm that Britain had conspired with Israel and France to manufacture a military pretext, and that his subsequent denials to Parliament were deliberate lies. The destruction was itself confirmed by participants in later accounts.
How did Eisenhower force the British withdrawal?
The US threatened to withhold IMF support for sterling at a moment of severe currency crisis. Britain, running out of dollar reserves as the pound came under speculative pressure, could not sustain the military operation without US financial backing. Eisenhower's economic leverage was decisive. The episode is a landmark case study in the limits of post-war British imperial power.
When was the Sèvres collusion publicly confirmed?
The Israeli State Archives declassified the Israeli copy of the Protocol in 1996. Historian Avi Shlaim published his comprehensive analysis in The Iron Wall (2000). French archival copies were also identified. For the preceding forty years, British governments had officially denied any foreknowledge of Israeli military action.
