A chief minister is an elected or appointed head of government of – in most instances – a sub-national entity, for instance an administrative subdivision or federal constituent entity. Examples include a state (and sometimes a union territory) in India; a territory of Australia; a province of Sri Lanka or Pakistan; a federal province in Nepal; an autonomous region of Philippines; or a British Overseas Territory that has attained self-governance. It is also used as the English version of the title given to the heads of governments of the Malay states without a monarchy. The title is also used in the Crown Dependencies of the Isle of Man (since 1986), in Guernsey (since 2004), and in Jersey (since 2005). In 2018 Sierra Leone, a presidential republic, created the role of an appointed chief minister, which is similar to a prime minister in a semi-presidential system. Before that, only Milton Margai had the same position between 1954 and 1958. From Wikipedia
