The leaders of the two Houses were of equal status, before 1911, unless one was the most recent Prime Minister for the party. Such a former prime minister was considered to be the overall leader of the opposition. From 1911 the Leader of the Opposition in the House of Commons was considered to be the overall Leader of the Opposition. Overall leaders names are bolded. Acting leaders names are in italics unless the acting leader subsequently became a full leader during a continuous period as leader.
