A political radical, Davies was elected to Caernarfonshire
County Council in 1904, later becoming an
alderman. He entered
Parliament in June 1906 when he was returned unopposed in a
by-election for the
Eifion division of Caernarfonshire, when the former
Member of Parliament John Bryn Roberts was appointed a
county court judge. Eifion had been held by Roberts, a Liberal in the
Gladstonian tradition, since its creation for the
1885 general election and at the
1906 general election Roberts had also been returned unopposed. Davies retained the Eifion constituency until
1918. During his years in Parliament, Davies sat on committees investigating land reform, the jury system, reform of the electoral system, compulsory purchases by local authorities, and reform of the
House of Lords. He returned to Parliament as MP for
Denbigh in
1923, but resigned in 1929 on grounds of ill health. In 1932, he was prominent in the discussions of the
Presbyterian Church of Wales on formulating a parliamentary bill relating to the church. ==Davies and Lloyd George==
