The King also proposes a candidate for Prime Minister, which is probably the King's most 'political' function, as he traditionally holds meetings with the leaders of all the major political parties in order to facilitate the formation of a government. If a candidate is successfully invested by the Parliament, he formally names him Prime Minister of Spain. When a Prime Minister has been named, he also formally names all the members of his government, all of which are proposed by the Prime Minister himself. The King has both a right and a duty to be informed of all the state affairs; he is also allowed to preside over the government meetings when the Prime Minister invites him to do so, although he has the ability to reject this invitation.
