BUENOS AIRES, Argentina (AP) — A diplomatic crisis between historic allies Spain and Argentina expanded Tuesday as Spain announced the official withdrawal of its ambassador from Buenos Aires and Argentine President Javier Milei lambasted the move as “nonsense typical of an arrogant socialist.”

Spain said its ambassador to Argentina would remain indefinitely in Madrid, where she had been recalled for consultations Sunday in response to comments made by President Milei during a contentious weekend visit he made to the Spanish capital. In a fiery speech defending free market capitalism at a far-right rally in Madrid, Milei accused the Spanish prime minister’s wife of corruption and described socialism as “cursed and carcinogenic.”

Following Milei’s refusal to apologize, Spanish Foreign Minister José Manuel Albares told reporters Tuesday that “Argentina will continue without an ambassador.”
