The Pope is "ex officio" sovereign of the Vatican City State since 1929. He delegates executive authority to the President of the Pontifical Commission for Vatican City State, who is "ex officio" President of the Governorate and head of government of Vatican. The president is appointed by the Pope for a five-year term, but may be removed at any time by the pope. The president reports all important matters to the Secretariat of State, the Pope's chief everyday advisory body, which is consulted on all matters, even if they belong to the specific competence of the Commission for Vatican City State or, for instance, that of the Congregation for Catholic Education. The Secretariat of State is not thereby considered to hold responsibility for such matters, and the Cardinal Secretary of State is not seen as heading the Vatican City State or the various departments of the Roman Curia, other than the Secretariat of State itself.
