Labour government, 1974–1979
In March 1976, having just turned sixty years old, Wilson resigned as Prime Minister, ending his leadership of the Labour Party after thirteen years, and a total of nearly eight years as Prime Minister. He was replaced by James Callaghan, who had held senior government positions during both of Wilson's ministries, and had served as a Shadow Cabinet member in the early-1960s.
Harold Wilson
The British "retreat from Empire" had made headway by 1964 and was to continue during Wilson's administration. Southern Rhodesia was not granted independence, principally because Wilson refused to grant independence to the white minority government headed by Rhodesian Prime Minister Ian Smith which was not willing to extend unqualified voting rights to the native African population. Smith's defiant response was a Unilateral Declaration of Independence, on 11 November 1965. Wilson's immediate recourse was to the United Nations, and in 1965, the Security Council imposed sanctions, which were to last until official independence in 1979. This involved British warships blockading the port of Beira to try to cause economic collapse in Rhodesia. Wilson was applauded by most nations for taking a firm stand on the issue (and none extended diplomatic recognition to the Smith régime). A number of nations did not join in with sanctions, undermining their efficiency. Certain sections of public opinion started to question their efficacy, and to demand the toppling of the régime by force. Wilson declined to intervene in Rhodesia with military force, believing the British population would not support such action against their "kith and kin". The two leaders met for discussions aboard British warships, in 1966 and in 1968. Smith subsequently attacked Wilson in his memoirs, accusing him of delaying tactics during negotiations and alleging duplicity; Wilson responded in kind, questioning Smith's good faith and suggesting that Smith had moved the goal-posts whenever a settlement appeared in sight. The matter was still unresolved at the time of Wilson's resignation in 1976.
