Sydney Arnold, 1st Baron Arnold

He unsuccessfully contested the Conservative seat of Holderness Division of the East Riding of Yorkshire at the December 1910 General Election. He was elected in 1912 as Member of Parliament for Holmfirth in what was then the West Riding of Yorkshire at a by-election following the resignation of the long-serving Liberal MP Henry Wilson. In 1914, he was appointed Parliamentary Private Secretary to Jack Pease, the President of the Board of Education. He was also appointed Parliamentary Private Secretary to Edwin Samuel Montagu the Financial Secretary to the Treasury. During the war he served as a captain in the South Staffordshire Regiment. He resigned that seat due to ill-health in 1921. ==Labour party==

In 1922, he joined the Labour Party and was ennobled in 1924 as Baron Arnold, of Hale in the County of Chester, and served as Under-Secretary of State for the Colonies in Ramsay MacDonald's short-lived 1924 Labour Government, and as Paymaster General from 1929 to 6 March 1931 in Macdonald's second government. In the late 1930s, he was a member of the Parliamentary Pacifist Group. He also served as a member of the council of the Anglo-German Fellowship. He resigned from the Labour Party, in 1938, on account of disagreement with its Foreign Policy. Subsequently, his name was one of twenty-six attached to a letter printed in The Times supporting a policy of appeasement towards Germany. Because signatories included Barry Domvile and other leading members it was dubbed "The Link Letter" and its various signatories, including political moderates such as Arnold, William Harbutt Dawson, Smedley Crooke and Lord Londonderry, came under suspicion as far right supporters. ==Arms==
