Joseph Montague Kenworthy, 10th Baron Strabolgi (7 March 1886 – 8 October 1953), was a Liberal and then a Labour Party Member of Parliament in the United Kingdom.
Strabolgi was born at Leamington in Warwickshire and educated at the Eastman's Royal Naval Academy at Northward Park in Winchester and as a cadet on H.M.S. Britannia, joining the Royal Navy in 1901 and served for seventeen years. His first posting as a naval cadet was in January 1903 to the battleship HMS Goliath,[1] serving on the China Station. During World War I, he was for a short period in the Plans Division of the Admiralty War Staff. He left for an appointment in the Mediterranean which enabled him to see the latest developments of war on seaborne commerce at close quarters. He returned to the Grand Fleet in time to be present at the final surrender of German sea power. He retired from the Navy in 1920 after entering Parliament.
Kenworthy first tried to enter Parliament at the 1918 general election contesting Rotherham as a Liberal but finished in third place. He was soon given another chance though when he was selected to contest Central Hull at a by-election in 1919. Anti-Coalition government sentiment was riding high and he was duly elected Member of Parliament for the Liberals. Kenworthy was one of the more energetic supporters of H. H. Asquith in Parliament and never lost his hostility to Lloyd George. During the 1924-29 parliament which was dominated by a Conservative majority, he worked closely with a group of radical Liberal MPs that included: William Wedgwood Benn, Percy Harris, Frank Briant and Horace Crawfurd to provide opposition to the government.[2] When Lloyd George became Leader of the Liberal Party in 1926, despite the party taking on a more radical hue, Kenworthy resigned from the party and joined Labour. He also resigned his seat in the House of Commons and fought and won a by-election in Central Hull, standing for Labour. He retained the seat until 1931.
He was an active supporter of the movement for the independence of India. In 1934, he succeeded his father as Lord Strabolgi and was the opposition chief whip in the House of Lords from 1938 to 1942. He was disappointed not to be given a position in the postwar Labour government (1945–51).
Lord Strabolgi married twice. Firstly, in 1913, he married Doris Whitley, daughter of his fellow Liberal MP, Frederick Whitley-Thomson. They had four children, and divorced in 1941. Later that year, he married Geraldine Francis.
When he died in 1953 aged 67, he was succeeded by his eldest son, David Montague de Burgh Kenworthy, 11th Baron Strabolgi, another left-wing politician and member of the Labour Party.
During World War II, he wrote numerous articles on the war, especially the war at sea. These include Secret Weapons in Modern World (27 April 1940) and What's Wrong with the British Army? in Colliers magazine (22 August 1942).
