The United States and several Latin American governments have expressed concern about unsupported claims that could undermine confidence in Colombia's presidential election. Conservative candidate Abelardo de la Espriella won a closely contested vote, while political opponents raised questions about campaign conduct, artificial intelligence content and possible foreign influence. International partners have called for a peaceful and constitutional transfer of power. The controversy reflects wider political polarisation across Latin America, where closely fought elections increasingly produce accusations of fraud, media manipulation and outside interference even when official results are accepted by electoral authorities.
