Diplomatic relations between Brazil and Nicaragua have deteriorated sharply following the mutual expulsion of ambassadors, spurred by tensions over Nicaragua's government actions. Brazilian President Luiz Inácio Lula da Silva expelled Nicaragua's ambassador in response to Nicaragua's expulsion of the Brazilian ambassador, which was a reaction to the latter's absence from a national celebration. This incident underscores the growing rift between Lula and Nicaraguan President Daniel Ortega, particularly regarding Ortega's crackdown on dissent and persecution of political opponents. Lula's government had previously sought to mediate tensions in Venezuela, complicating its diplomatic efforts in the region. The situation reflects a broader shift in Lula's foreign policy as he recalibrates his stance towards leftist leaders, amidst criticisms for his leniency towards authoritarian regimes. The mutual expulsions signal a significant diplomatic breakdown between two nations historically aligned on leftist ideologies.
