The term "head of government" is often differentiated from the term "head of state", (e.g. as in article 7 of the Vienna Convention on the Law of Treaties, article 1 of the Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons, including Diplomatic Agents and the United Nations protocol list), as they may be separate positions, individuals, or roles depending on the country . </P> <P> The authority of a head of government, such as a president, or prime minister and the relationship between that position and other state institutions, such as the relation between the head of state and of the legislature, varies greatly among sovereign states, depending largely on the particular makeup of the government that has been chosen, won, or evolved over time . </P>
