Colombians have failed to elect a president outright, setting the stage for a bitter runoff between two frontrunners from opposite ends of the political spectrum, while a peace process with leftist rebels hangs in the balance.Iván Duque, a hardline conservative who viscerally opposes the peace accord, took the largest share of the vote on Sunday with 39%, though fell short of the 50% required to win at the first round. Instead, he will face Gustavo Petro – a leftwinger and former mayor of Bogotá, who came second with 25% – in the second round on 17 June.Petro, himself once a guerrilla, was Colombia’s first progressive candidate in generations and had been expected to gain a larger share. But a third candidate, the more moderate Sergio Fajardo, appeared to siphon off Petro’s support, receiving 23%. It remains to be seen if Fajardo, a reformer and former mayor of Medellín, will back Petro in the second round.The two other candidates, Germán Vargas Lleras and Humberto de la Calle, were unable to muster 10% of the vote between them.(theguardian)…[+]
