The prime minister of Spain is the head of the government of Spain. Under Article 99 of the Constitution of Spain, the prime minister is appointed by the king of Spain on the nomination of the Congress of Deputies, the lower house of the Cortes Generales.Constitution of Spain, Article 99. The candidate for the position of prime minister is not required to be a member of Congress.

After a general election or the resignation of a prime minister, members of Congress are proposed by the king for the position of prime minister. There can be only one candidate per session. If the Congress of Deputies, by the vote of the absolute majority of its members, gives its confidence in said candidate, the king will appoint them as prime minister. If said majority is not reached, the same proposal will be submitted to a new vote forty-eight hours after the previous one, and trust will be deemed granted if a simple majority is obtained.

The Constitution of Spain came into operation on 6 December 1978, following the dictatorship of Francisco Franco and the Spanish transition to democracy.
