Houghton was a great believer in equality of opportunity and campaigned for certain numbers of lower (clerical) grade civil servants to have the chance of taking an examination that could lead to previously unheard-of promotion . In 1922, he founded the
Inland Revenue Staff Federation and was its leader from 1922 to 1960. He served on the General Council of the
Trades Union Congress from 1952 to 1960, and as Chairman of the Staff Side Civil Service
National Whitley Council from 1955 to 1957. He was a panel member of a BBC radio programme
Can I help You? between 1941 and 1964. His connections with the
London Labour movement and the Labour Party gave him the profile to become an
Alderman of the
London County Council - the forerunner of the
Greater London Council - from 1947–1949. After
John Belcher quit the
House of Commons over accusations of minor dishonesty, Houghton was persuaded to seek nomination for the subsequent by-election. He secured this and on 16 March 1949 was elected to Parliament for the
Yorkshire constituency of
Sowerby with a majority of 2,152. He was re-elected in the subsequent general elections of 1950, 1951, 1955, 1959, 1964, 1966 and 1970. His head for figures and tenacity made him a good candidate for Chairman of the
Public Accounts Committee in the House of Commons, succeeding
Harold Wilson in this post after Wilson was elected Leader of the Labour Party in 1963. When, after 13 years in government, the
Conservative Party was defeated in October 1964, Houghton became a
cabinet minister in Wilson's first government and was appointed a
Privy Counsellor. The post of
Chancellor of the Duchy of Lancaster after 1964 gave Houghton a position in the cabinet and special responsibility for
Social Services but not an actual department over which he could preside. This made it hard to be particularly effective as a minister, and in a 1966 reshuffle, Wilson made him
Minister without Portfolio. Houghton became a
Member of the Order of the Companions of Honour on 5 January 1967 and was dropped from government in 1967 and became Chairman of the
Parliamentary Labour Party (PLP) which is a post designed to help shape and reflect the backbench Labour MPs' views but keep them in dialogue with the Labour leadership. His predecessor,
Emanuel Shinwell, could be rather fiery and unpredictable. By contrast, Houghton had a tenacity and command of detail that made him a highly suitable person for the task, given there was perceived to be quite a lot of factionalism in the party at the time. He retired from the House of Commons at the February 1974 General Election and was elevated to the
House of Lords as
Baron Houghton of Sowerby, of Sowerby in the County of
West Yorkshire a few months later on 20 June. Shortly before he died in 1996, he was the last member of the House of Lords to have fought in the First World War, and at 97, was then its oldest serving member. ==Animal welfare==
