POLL-Right-wing Duque keeps edge ahead of Colombia's presidential…

BOGOTA, April 26 (Reuters) – Right-wing candidate Ivan Duque is holding onto a substantial lead over other contenders for the presidency ahead of Colombia’s May 27 election, with 38 percent of voters saying they plan to back him, a survey by YanHaas showed on Thursday.

Support for Duque, a protégé of former President Alvaro Uribe, was up 1 percent from the last survey by the Centro Nacional de Consultoria (CNC) and 2.6 points ahead of the most recent numbers published by Cifras y Conceptos. Leftist candidate Gustavo Petro, a former M-19 rebel and previous mayor of Bogota, was in second place with 28 percent, down slightly from the last poll by CNC.

Centrist Sergio Fajardo came third with 11 percent and support for center-right German Vargas Lleras was 7 percent.
