Elliot then became involved in Conservative affairs, wrote speeches for, and campaigned in elections for, her husband, as well as promoting his enactment of the
Milk Marketing Board. Still in touch with her Liberal roots, she favoured
prison reform and was an opponent of
capital punishment. From 1939 to 1949, Elliot was chair of the National Association of Mixed Clubs and Girls' Clubs (later known as
Youth Clubs UK) and she sat on the
Home Office advisory committee on the treatment of offenders from 1946 to 1962, during which time she visited every prison in the kingdom. She also served on the advisory committee on child care in Scotland from 1956 to 1965, was chair of the
Conservative Women's National Committee from 1954 to 1957 and was chair of the
National Union of Conservative and Unionist Associations from 1956 to 1967. She became the first chair of the
Consumer Council in 1963. On three occasions, in 1954, 1956 and 1957, she was a member of the UK delegation to the
United Nations and in the absence of ministers during the
Suez Crisis in 1956, she made a speech denouncing the
Soviet invasion of
Hungary during the
Hungarian Revolution of 1956. She was appointed a
Commander of the Order of the British Empire in 1946, awarded the Grand Silver Cross of the
Order of Merit of Austria in 1963. In a 1958 episode of the
BBC television programme
The Brains Trust she described herself as an "unrepentant defender of votes for women". Following the death of her husband in 1958, Elliot took over from him as chair of the family auctioneering firm and stood in his place as parliamentary candidate of
Glasgow Kelvingrove, but lost by a narrow margin of votes to the Labour candidate
Mary McAlister in the
1958 Glasgow Kelvingrove by-election. ==House of Lords==
