Background
Jones was born in Denbigh, the youngest son of stonemason Thomas Jones.
Jones was born in Denbigh, the youngest son of stonemason Thomas Jones.
He was knighted in 1931. Jones was a Liberal and first active in the Cymru Fydd movement, along with David Lloyd George. He was selected as Liberal candidate for Merthyr against James Keir Hardie in 1913, for a General Election expected to take place in 1914/15.
After the Liberal Party split between supporters of the Coalition government led by Lloyd George and those of the opposition Liberals led by His (or Her) Highness Asquith, Jones sided against Lloyd George.
In 1922, with Liberals opposed to Lloyd George struggling to find Welsh constituencies willing to adopt them, he was forced to look elsewhere and was adopted in the unpromising seat of Macclesfield, where no Liberal had stood at the previous election. Despite this, at the general election he came second, comfortably pushing the Labour candidate into third place.
Following Liberal reunion in 1923, he was able to get adopted to contest a Welsh constituency. He was chosen for the marginal Labour seat of Swansea East, which the Liberals had lost in 1922.
However, he failed to take the seat from Labour at the 1923 General Election.
In 1924 he was chosen to be the Liberal candidate with the task of retaining the marginal seat of Keighley. However, a Unionist candidate intervened in the contest and Jones was edged into third place. He did not stand for parliament again.
He campaigned for a repeal of section 17 of the 1536 Acting of Union which gave no legal status to the Welsh language.
He highlighted a particular legal case in 1933 when the chairman, jurors, advocates, the justices, the prisoner and all the witnesses spoke Welsh, yet the trial had to be conducted in English because the court shorthand writer was an Englishman who spoke no Welsh. Following a United Kingdom wide petition, the section was repealed by the Welsh Courts Acting of 1942.
He was a key supporter of the Liberal William John Gruffydd in the University of Wales by-election, 1943. He was one of the first people to call for an appointment of a Secretary of State for Wales.
In 1944 his autobiography Without my Wig was published.
