What three countries signed a secret agreement to seize control of the Suez canal?

In October 1956, the United Kingdom, France, and Israel signed a secret agreement known as the Sevres Protocol to seize control of the Suez Canal. This agreement was part of a strategy to regain Western control over the canal following its nationalization by Egyptian President Gamal Abdel Nasser. The operation, however, faced significant international backlash and was ultimately unsuccessful, leading to a withdrawal of the invading forces.
