paragraph_text: Canadian sovereignty
  
  Under Laurier, and his successor William Lyon Mackenzie King, the Liberals promoted Canadian sovereignty and greater independence within the British Commonwealth. In Imperial Conferences held throughout the 1920s, Canadian Liberal governments often took the lead in arguing that the United Kingdom and the dominions should have equal status, and against proposals for an 'imperial parliament' that would have subsumed Canadian independence. After the King–Byng Affair of 1926, the Liberals argued that the Governor General of Canada should no longer be appointed on the recommendation of the British government. The decisions of the Imperial Conferences were formalized in the Statute of Westminster, which was actually passed in 1931, the year after the Liberals lost power.
  
  The Liberals also promoted the idea of Canada being responsible for its own foreign and defence policy. Initially, it was Britain which determined external affairs for the dominion. In 1905, Laurier created the Department of External Affairs, and in 1909 he advised Governor General Earl Grey to appoint the first Secretary of State for External Affairs to Cabinet. It was also Laurier who first proposed the creation of a Canadian Navy in 1910. Mackenzie King recommended the appointment by Governor General Lord Byng of Vincent Massey as the first Canadian ambassador to Washington in 1926, marking the Liberal government's insistence on having direct relations with the United States, rather than having Britain act on Canada's behalf.
