Griffith was one time chairman of the
National League of Young Liberals. He was well known as a good platform performer in politics and for being an outstanding young thinker ranked alongside the likes of Elliott Dodds. He contested the
Bromley division of
Kent for the Liberal party in the general elections of
1922,
1923 and
1924 being unsuccessful on all three occasions. By 1927, Griffith was so well thought of in Liberal circles that he was appointed to the Liberal Organizing Committee under the Chairmanship of future party leader
Herbert Samuel. Also appointed at the time was
Archie Sinclair, another future leader. In March 1928 he was adopted as candidate for
the by-election in the Liberal seat of
Middlesbrough West which he held in a three cornered contest. The deceased Liberal incumbent,
Trevelyan Thomson, had been so entrenched in the seat that he had been unopposed at the previous general election. However Labour put up a strong challenge against Griffith at the by-election, losing by just 89 votes. Griffith got 36.3% of the poll, compared to Labour's 36% and the Conservatives' 27.8%. Griffith fought mainly on the traditional Liberal stance of
Free Trade but also called for a programme of public works together with social reform and industrial reconstruction. as did Herbert Samuel. In 1931–32 Griffith was
parliamentary private secretary to Sir Herbert Samuel, by then the
Home Secretary and Liberal leader. Griffith's sister
Olga Collett gave speeches on behalf of her brother. ==Law==
