It was being controlled by the Suez company , which British had a huge amount of stock, so they were in semi control. Having said that, it was an anglo-french company. Meaning it was mainly supported/owned by the British and the French. (The Editors of Encyclopædia Britannica 2017) They also wanted to take back the canal, as I had stated before, the company was partly owned by the British, so Britain wants their canal back. Nasser took their canal, and they wanted it back. They also may want it back just so they can go back to normal. (U.S. Department of State 1953-1960)
As stated earlier the Suez company is also partly controlled by the French. They were also mad that Nasser took the canal because they also lost the control of the canal along with the British so they were also qualified to be mad at Nasser for taking the canal.(U.S. Department of State 1953-1960) Another huge factor was that they thought that Nasser and Egypt were supporting the Algerian rebellion. They were proven right when they found out more information. That got them even more mad than them just nationalizing the canal! (Jazeera
