The small group of opposition Liberals met in 1919, distanced by his coalition's protectionism and nationalization. They resolved that they were the Liberal Parliamentary Party. They elected Sir Donald Maclean as Chairman of the Parliamentary Party. Liberal Party practice at the time, when the overall leader of the party had lost an election to the House of Commons, was for the chairman to function as acting leader in the House. Maclean therefore took on the role of leader of the opposition, followed by Asquith, who returned to the House by winning a by-election (1920–22).
