Public role
Members of the Spanish Royal Family are often asked by non-profitcharitable, cultural, or religious organizations within and without Spain to become their patrons, a role the Spanish constitution recognizes and codified in Title II Article 62. It is incumbent for the monarch "to exercise the High Patronage of the Royal Academies". Royal patronage conveys a sense of official credibility as the organization is scrutinized for suitability. A royal presence often greatly raises the profile of the organization and attracts media publicity and public interest that the organization may not have otherwise garnered, aiding in the charitable cause or cultural event. Royalty make use of their considerable celebrity to assist the organization to raise funds or to promote government policy. Additionally, members of the royal family may also pursue their own charitable and cultural interests. Queen Sofía devotes much of her time to the Queen Sofia Foundation ; while Leonor, Princess of Asturias presents the annual Princess of Asturias Awards, which aims to promote "scientific, cultural and humanistic values that form part of mankind's universal heritage." The Princess of Asturias Foundation holds the annual Princess of Asturias Awards acknowledging the contributions of individuals, entities, and/or organizations from around the world who make notable achievements in the sciences, humanities, or public affairs. King Felipe VI serves as president of the Organization of Ibero-American States which hosts the annual Ibero-American Summit, serves as president of the Codespa Foundation, which finances specific economic and social development activities in Latin American and other countries, and serves as president of the Spanish branch of the Association of European Journalists, which is composed of achieving communications professionals. King Felipe VI also serves as honorary chair of the Ministry of Culture National Awards Ceremonies. Infanta Elena, Duchess of Lugo, Juan Carlos' elder daughter, is the Director of Cultural and Social Projects of Mapfre Foundation, while Infanta Cristina, Juan Carlos' younger daughter, served as the Goodwill Ambassador to the United Nations for the 2nd World Assembly on Ageing, and is a member of the Dali Foundation Board of Trustees, president of the International Foundation for Disabled Sailing, and Director of Social Welfare at the La Caixa Foundation in Barcelona where she lives with her family. King Juan Carlos, Queen Sofia, and Infanta Cristina are all members of the Bilderberg Group, an informal think-tank centered on United States and European relations, and other world issues.
