Local government From a young age, Finsberg was active in the Conservative Party, and was founder chairman of
Mansfield Young Conservatives from 1946 to 1947; this was the area where he was working as a Bevin Boy. He subsequently became chairman of the
Hampstead Young Conservatives, aged 22, at a time when the constituency had nearly 1,000 party members. Before he turned 23, Finsberg was elected as a councillor for the
Metropolitan Borough of Hampstead at the
1949 local elections, representing the West End ward. The same year, he became a member of the Executive Committee of the
National Union of Conservative and Unionist Associations, a role he would hold until 1979. Finsberg served as National Chairman of the Young Conservatives from 1954 to 1957. Following the Conservatives' election victory, he served in two junior ministerial roles, as
Parliamentary Under Secretary of State at the
Department of the Environment (1979–81), and the
Department of Health and Social Security (1981–83).
The Times later suggested that his inability to progress further "could have been because he lacked excitement. His public persona was dull; in private, he could be an amusing companion." That year, Finsberg again became a Vice-Chairman of the Conservative Party Organisation, holding this role until 1987. From 1986 to 1989, he was President of the Greater London Area Executive Committee of the National Union of Conservative and Unionist Associations. ==Outside Parliament==
