According to the 8 Squadron Association website:
Farwell to the Middle East
The Arab Israeli ‘six day war’ fought in October 1967 led to the closure of the Suez Canal. Aden had cut its ties with Britain, and the independence of several East African and South East Asian states had also diminished the importance of the Indian Ocean to Britain. Despite the importance of the Middle Eastern Oil fields, defence cuts in Britain hit the air force in the Middle East hard. Two of 8 Squadron’s Hunters were even sold to the Royal Jordanian Air Force as the Middle Eastern States formed their own air forces. Air Power and a British presence were no longer needed.
