Election watchdog Kontra Daya urged the Commission on Elections (Comelec) to extend voting hours due to reports of "vote counting machine (VCM) breakdowns."
The closing time of the election is set at 7 p.m. today.
"With the volume of reports coming in to Kontra Daya regarding vote counting machine (VCM) breakdowns, as well as the longer time required to vote due to enforcement of health protocols, there is a high probability that many voters would be unable to vote by 7 p.m." the group said in a statement.
"Kontra Daya has received reports of voters going home after being unable to wait due to long lines or the arrival of replacement machines. This is a clear case of voter disenfranchisement," it added.
The group said that by extending the voting hours, this will "enable more voters to cast their votes and allow time for Comelec to resolve issues with voting."
