Brazil has asked Argentina's ambassador to leave the country, the foreign ministry in Buenos Aires said Tuesday, amid a diplomatic spat sparked by Argentine President Javier Milei's repeated insults directed at Brazilian leader Luiz Inacio Lula da Silva. The escalation in tensions comes two days after Milei doubled down on derogatory remarks about Lula. The libertarian Argentine leader made similar remarks during a speech in Brazil last month supporting Flavio Bolsonaro, Lula's right-wing opponent in the upcoming presidential election. Brazil recalled its ambassador to Argentina for consultations over Milei's speech, but Buenos Aires later sought to downplay the spat, with presidential spokesperson Adrian Ravier saying it was a matter of "ideological and political differences." He was freed after his conviction was overturned on procedural grounds, with the presiding judge also later ruled to have been biased.
