Query: When did the last British troops leave Egypt?
Context: Nasser was informed of the British–American withdrawal via a news statement while aboard a plane returning to Cairo from Belgrade, and took great offense. Although ideas for nationalizing the Suez Canal were in the offing after the UK agreed to withdraw its military from Egypt in 1954 (the last British troops left on 13 June 1956), journalist Mohamed Hassanein Heikal asserts that Nasser made the final decision to nationalize the waterway between 19 and 20 July. Nasser himself would later state that he decided on 23 July, after studying the issue and deliberating with some of his advisers from the dissolved RCC, namely Boghdadi and technical specialist Mahmoud Younis, beginning on 21 July.
