The moderate candidate in Honduras's knife-edge presidential election, Salvador Nasralla, has alleged "unscrupulous individuals" of tampering with the vote count in the country.
Over a week after the election, the electoral council has still not declared a winner, but the most recent tally suggest that Nasry "Tito" Asfura, the right-wing contender endorsed 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 theft."
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, ahead of Nasralla with under forty percent and Moncada with 19.32%, according to the National Electoral Council's (CNE) update.
Patience has worn thin over the last week as the counting stalled several times, sometimes for extended periods.
Representatives of the CNE blamed "system glitches."
They have also cautioned that numerous voting records with "inconsistencies" still need to be examined.
The run-up to the election was dominated by Trump's support for Nasry "Tito" Asfura.
Just days before the vote, Trump threw his weight behind the former mayor of Tegucigalpa, saying that "We can work together to fight the Narcocommunists."
"We will be very supportive should Asfura win, but the United States will not be throwing good money after bad, because a wrong Leader can only bring disastrous outcomes," Trump added.
In a surprise move two days before the election, Trump also granted clemency to jailed former Honduran president Juan Orlando Hernández, who is from the same party as Asfura.
Hernández was in the midst of a 45-year prison sentence in the US for trafficking cocaine.
His clemency and freedom has shocked Honduran authorities, who have issued an international arrest warrant for Hernández, who is still in the US.
Meanwhile, the situation has grown more tense as the lead in the vote count fluctuated repeatedly.
Trump claimed the CNE of "seeking to alter" 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 "meddling and pressure of the President of the United States."
Nasralla blamed unnamed "corrupt ones" for "delaying the counting process."
According to the nation's regulations, the CNE has until 30 December to declare a winner.
