It is also used as the English version of the title given to the heads of governments of the Malay states[3] 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).
[5] The title has a similar construction and role as a first minister or minister-president but usually with a lower rank.
The role has context within the Westminster system of government where a constitutional head of state (usually sub-national) is advised by ministers who usually head executive government departments (ministries).
They would be the chief adviser to the nominal head of their state, the chair of cabinet and leader of the main governing political party in the legislature.
