In the 1920s Mrs Runciman took on a more national political role. She served as president of the Women's National Liberal Federation, 1919–21, continuing to sit on its executive committee for many years. She also served as president of the Women's Free Church Council, was a member of the executive of the League of Nations Union, chaired the Westminster Housing Association and was a founder of the Westminster Housing Trust. In Liberal Party politics, she was a strong advocate of H. H. Asquith, and under her presidency, the Women's National Liberal Federation supported the maintenance of independent Liberalism and an end to the Lloyd George coalition.[3]
Parliament
She became an MP in her own right in 1928, when she was elected in a by-election as Member of Parliament for St Ives in Cornwall, but she remained in Parliament for only one year and handed the seat to her husband at the 1929 general election. The 'halo effect' of women taking a parliamentary seat and then handing it over to their husband accounted for the election of ten women MPs (nearly a third of the women elected to Parliament) between both World Wars.[4]
She herself fought the 1929 general election for the Liberals at Tavistock and had been invited to become the candidate by the local Liberal Association against the wishes of national headquarters, which was apparently unhappy that she was not a supporter of the party leader David Lloyd George.[5] She narrowly failed to gain Tavistock from the Conservatives by just 152 votes.[6]
