 "Premier" is also the title of the heads of government in sub-national entities, such as the provinces and territories of Canada, states of the Commonwealth of Australia, provinces of South Africa, the island of Nevis within the Federation of Saint Kitts and Nevis, and the nation of Niue.In some of these cases, the formal title remains "Prime Minister" but "Premier" is used to avoid confusion with the national leader.In these cases, care should be taken not to confuse the title of "premier" with "prime minister".
