Despite Cepeda’s concession, radical Marxists in Colombia marked de la Espriella’s election with violent riots and Petro used his position in office to claim fraud. “Foreigners committed with foreign money the electoral fraud that imposes a president who did not win the election,” he continued. “The electoral regime in Colombia must change substantially if we don’t want more violence,” Petro claimed. “It is very clear that what can happen is a civil war in Colombia,” he continued. De la Espriella has vowed a heavy-handed approach against public disorder and crime, as he had campaigned on, and addressed the possibility of leftist riots in an online address on Sunday.
