Security is one of the central issues of the May 31 presidential election. Political violence was brought into sharp focus last June, when young conservative presidential frontrunner Miguel Uribe Turbay was shot in broad daylight while campaigning in the capital Bogota and later died from his wounds.

Leftist Senator Ivan Cepeda, an architect of Petro’s controversial policy of negotiating with armed groups, is ahead in polls.

He is trailed by right-wing candidates Abelardo de la Espriella and Paloma Valencia, both of whom have pledged to take a hard line against rebel groups.

All three have reported receiving death threats and are campaigning under heavy security.
