Torcuato Fernández-Miranda, the president of the Council of the Realm, placed Adolfo Suárez on a list of three candidates for King Juan Carlos to choose to become the new head of government, replacing Arias Navarro. The king chose Suárez because he felt he could meet the challenge of the difficult political process that lay ahead: persuading the Cortes, which was composed of appointed Francoist politicians, to dismantle Franco's system. In this manner, he would formally act within the Francoist legal system and thus avoid the prospect of military intervention in the political process. Suárez was appointed as the 138th Prime Minister of Spain by Juan Carlos on 3 July 1976, a move opposed by leftists and some centrists given his Francoist past.
