conference, he befriended a member of the American delegation, the Assistant Navy Secretary and a rising star in the Democratic Party, Franklin D. Roosevelt, which later became an important factor in his career when Roosevelt was elected president in 1932. He was appointed a Companion of Honour (CH) in March 1920. In March 1921, Kerr left Lloyd George's service to become the editor of The Daily Chronicle, a newspaper that Lloyd George had purchased in 1918. As editor, Kerr favored the Liberals in his leaders (editorials). Kerr was a director of United Newspapers from 1921 to 1922 and secretary to the Rhodes Trust from 1925 to 1939. In August 1922, Kerr delivered three lectures at the Institute for Politics in Williamstown, Massachusetts entitled On the Prevention of War.

In the same speech, Kerr claimed the Treaty of Versailles was amoral because it was based on the "lie" that Germany started the war in 1914, which Kerr claimed was the work of many states. In March 1930 he succeeded his cousin as the 11th Marquess of Lothian and entered the House of Lords. In May of the following year he was made a Deputy Lieutenant of Midlothian. After the formation of the National Government in August 1931, Lothian was appointed Chancellor of the Duchy of Lancaster by Ramsay MacDonald. In November of the same year he became Under-Secretary of State for India, a post he held until 1932, when he was replaced by Rab Butler. Lothian was a key driving force behind the National Trust Act of 1937, using
