What did the anglo-egyptian treaty promise?

The Anglo–Egyptian Treaty ("Heads of Agreement") was signed on 27 July 1954, ending more than seventy years of British occupation of the Suez Canal Zone. When Britain relinquished its military presence in other parts of Egypt after the end of the Second World War, it continued to keep its forces in scores of camps, a number of airfields, and other military installations along the Canal. Despite the British withdrawal from India and other colonies "East of Suez" in the late 1940s, British and U.S. strategists continued to consider the installations along the Canal vital in case of war with the Soviet bloc.
