In the
1929 general election, Errington was an unsuccessful candidate in
Hanley for the
Conservative Party. He fought
Liverpool Scotland in the
1931 general election, becoming one of the few Conservative candidates to be defeated in the election. He was elected to
Liverpool City Council for the
Aigburth in
1934. Having served his 'apprenticeship' in unfavourable seats, Errington had an opportunity in a winnable seat in the
1935 general election. He managed to win
Bootle, and sat in
Parliament for ten years. During the
Second World War he enlisted in the
Royal Air Force and served from 1939 to 1945. In the Labour landslide
1945 general election, however, Errington lost his seat. Out of Parliament Errington remained involved in Conservative politics and was made Chairman of the North Western Area of the
National Union in 1946 (a position he held until 1951). In 1948 he became a
Justice of the Peace in Liverpool, an appointment facilitated by political party membership. In 1952 he became chairman of the executive committee of the
National Union of Conservative and Unionist Associations. He was
knighted in the
1952 Queen's Birthday Honours List. Abandoning Liverpool, Errington became MP for
Aldershot in
Hampshire in
an October 1954 byelection. He held the safe seat until he retired in 1970. He was involved in business and was President of the National Federation of Property Owners from 1956 to 1959, and of the Hire Purchase Trade Association in 1965. From 1961, Errington's seniority in Parliament brought him the Chairmanship of the Estimates Sub-Committee on Home Affairs. He was also President of the Wessex Provincial Area of the National Union from 1962 to 1965. In 1963 he was made a
baronet. He died on
Anglesey aged 73. ==Personal life==
