Answer
Robert Borden, who served as Prime Minister of Canada from 1911 to 1920, was succeeded by Arthur Meighen. Meighen, a Conservative Party member, took office on July 10, 1920, after Borden's resignation due to health reasons. Meighen's premiership was marked by economic challenges and political instability, leading to his defeat in the 1921 federal election by the Liberal Party under William Lyon Mackenzie King.
