There was British influence in that area as Britian occupied Egypt in 1882 and took over control of the Egyptian govt's share of the Suez Canal. The Suez canal played an important role as it cut down on the time it took to Africa. It was also the gateway to India and there was a threat of Russian expansion in this area, so Britain wanted to gain a foothold in the area.
Historians argue as to the reasons for the occupation. Robinson and Gallagher argue that it was imperialist, as France was already a rival in Egypt. Cain and Hopkins see it as "gentlemenly capitalism" Britain also had its own interests as Disraeli's govt. had bought shares in the Suez canal in 1875 and Gladstone had personally invested money.
During the war, it was used strategically as Britain closed the canal to non-allies.
Not sure if this is the historian you are after but Keith Wilson argues that British imperialism was the most important factor in national interests.
Hope that helps!I had a history exam last week and that's some of what I wrote!
