How far was the strength of conservative leadership the main reason for their political dominance of the period 1951-1964?
From 1951 to 1964 the conservative government won 3 general elections and spent 7 years in power. From 1951 to 1955 Winston Churchill was the leader of the conservative party, from 1955 to 1959 Anthony Eden held the reign of the party and 1959 to 1964 Harold Macmillan was the leader and they all became Prime Minister. The conservative run ended when Douglas Home became the leader of the party and lost his election to Wilson. The factor of strong conservative leadership strength is important when discussing why they were politically dominating but there are other factors which we can also judge as potential main reasons for why they were in power for seven years.
Conservative leadership from 1951 was very strong. Churchill led the party and was very favourable with the public because he helped in the efforts to win the Second World War and was a key figure in British politics because of his experience. Anthony Eden was an attractive and charismatic individual who gained a lot of support for younger voters but especially women. In despite being a good leader who was in control of his party his reputation perished from his actions of the Suez crisis and tarnished the reputation of Britain, making the once powerful empire now look expendable.
