The moderate candidate in Honduras's tightly contested presidential election, Salvador Nasralla, has accused "unscrupulous individuals" of tampering with the vote count in the Central American nation.
Over a week after the election, the electoral council has yet to announce a winner, but the latest results suggest that Nasry "Tito" Asfura, the right-wing contender backed by US President Donald Trump, holds a narrow lead.
Nasralla, who had been leading earlier on before falling to second place, stated on social media: "This is a robbery."
The progressive hopeful placed in third, Rixi Moncada, has called for the vote to be annulled and alleged US interference by Trump in the election.
With the vast majority of votes counted, Asfura had just over forty percent of the vote, leading Nasralla with under forty percent and Moncada with 19.32%, according to the election body's update.
Frustration has been growing over the last week as the counting stalled several times, sometimes for extended periods.
Officials from the CNE attributed the delays to "technical problems."
They have also warned that thousands of voting records with "discrepancies" still need to be reviewed.
The run-up to the election was overshadowed by Trump's endorsement of Nasry "Tito" Asfura.
Just days before the vote, Trump backed the former mayor of Tegucigalpa, saying that "Tito and I can work together to fight the Narcocommunists."
"Our support will be strong should Asfura win, but we will not be wasting resources, because a wrong Leader can only bring catastrophic results," Trump added.
In a unexpected action two days before the election, Trump also granted clemency to jailed former Honduran president Juan Orlando Hernández, who stems from the same party as Asfura.
Hernández was serving a 45-year prison sentence in the US for conspiring to import cocaine.
His pardon and subsequent release has shocked Honduran authorities, who issued an international arrest warrant for Hernández, who is still in the US.
At the same time, tension has been rising as the lead in the vote count fluctuated repeatedly.
Trump accused the CNE of "trying to change" the outcome when Nasralla pulled past Asfura early on.
"They will face severe consequences," the US president said without providing evidence of any fraud.
Ever since the Trump-endorsed Asfura moved in the lead, it has been his two rivals alleging misconduct.
Rixi Moncada's Libre party called for the "the total annulment" of the elections.
It also urged its supporters to take to the streets against what it called "the interference and coercion of the President of the United States."
Nasralla blamed unnamed "bad actors" for "delaying the counting process."
According to the nation's regulations, the CNE has until 30 December to announce a victor.
