(BOGOTA, Colombia) — Ivan Duque, the young conservative protege of a powerful former president, was elected Colombia’s next leader Sunday after promising to roll back a fragile peace accord that has divided the South American nation. Duque captured almost 54% of the vote, putting him 12 points ahead of former leftist guerrilla Gustavo Petro in a tense runoff election that had appeared to be tightening in recent days. In the end, the prematurely graying 41-year-old sailed to victory, promising to change parts of the accord with leftist rebels but not “shred it to pieces” as some of his hawkish allies had been urging. When he takes office in August, Duque will be Colombia’s youngest president in more than a century. “The peace we all dream of demands corrections,” he told hundreds of jubilant supporters.
