In November 2007, at the Ibero-American Summit in Santiago de Chile, during a heated exchange, Juan Carlos interrupted Venezuelan President Hugo Chávez, saying, ""¿Por qué no te callas?"" ("Why don't you shut up?"). Chávez had been interrupting the Spanish Prime Minister, José Luis Rodríguez Zapatero, while the latter was defending his predecessor and political opponent, José María Aznar, after Chávez had referred to Aznar as a fascist and "less human than snakes". The King shortly afterwards left the hall when President Daniel Ortega of Nicaragua accused Spain of intervention in his country's elections and complained about some Spanish energy companies working in Nicaragua. This was an unprecedented diplomatic incident and a rare display of public anger by the King.
