Honduras' ruling party presidential candidate Nasry Asfura remains the favourite ahead of the Nov. 28 election. It’s a boost to backers of the country's current government.
The poll was conducted by CID-Gallup published on Friday. It showed Asfura, mayor of the capital Tegucigalpa and candidate of the ruling National Party, received 21 percent support among those polled, one percentage point up from a previous survey published in May.
His closest rival is Xiomara Castro, wife of former President Manuel Zelaya, got 18 percent. Castro is running for the leftist Liberty and Refoundation Party (LIBRE).
Television presenter Salvador Nasralla, put forward as a candidate by a coalition of parties, also came in with 18 percent support.
The poll also showed that the number of Hondurans who plan not to vote at all has risen to 18 percent from 12 percent earlier.
The candidates are seeking to replace outgoing two-term President Juan Orlando Hernandez, whose eight years in power have been mired by corruption allegations.
Hernandez has denied the accusations, including by prosecutors in a US trial that he worked with drug traffickers to move large quantities of cocaine into America.
