Honduras is set to elect a woman as president, despite ongoing allegations of fraud and a renewed crack-down on the country’s left-wing opposition.
If leftist Salvador Nasralla wins on Sunday, he will become the first president ever from the country’s large Indian community.
Nasralla is trailing challenger Juan Orlando Hernandez in the presidential count.
But the ruling National Party says there is no evidence of major irregularities.
“It’s this faction that is committing such crimes,” Mr Hernandez told the BBC’s Global Politics programme in May.
“This will be a huge moment for our country.”

Analysts say that even if he loses the election, he could still win the presidency by forming an alliance with another rival.
Mr Nasralla has pushed forward in the elections despite alleging widespread vote-rigging and alleged corruption by the National Party.
Two people died after a political rally by his Anticorruption Party (PAN), though no guns were used, officials said.
What do the two main candidates stand for?
Ms Nasralla is the candidate of the Anticorruption Party (PAN), which calls for a clean break with previous administrations.
Mr Hernandez, the current president, also leads the National Party and is running for a second term in office.
He has promised increased development, jobs and government subsidies for poor Hondurans.
Mr Nasralla’s supporters hope he will help to end corruption in Honduras, which has experienced 12 presidents since the first republic was set up in the mid-1800s.
Honduras has a sizeable Indian population, and they feel a lack of political representation from the major parties.
The BBC’s Martin Sandvin in Tegucigalpa says a win for Mr Nasralla would have a major impact, given the fact that women have never been elected president in the country’s 117-year history.

What does the opposition claim?
The opposition says thousands of voters were turned away in elections held last month.
They also claim to have seen vote-buying and organised electoral fraud in previously undemocratic regions.
However, polls suggest voters are more concerned with concerns about crime and insecurity in Honduras.
Which parties will be affected by the protests?
The elections have not been without its problems.
During the campaign there were allegations of vote-buying, campaigns were marked by violence, and activists were murdered.
Do the United States and Mexico still have influence in Honduras?
Mr Nasralla has worked closely with the USAID, a major aid agency, and Petrocaribe, a trade arrangement between countries in the Caribbean and Latin America that provides subsidized oil to impoverished citizens.
He has demanded the US must not interfere in the electoral process, and assured critics that he was “not a puppet of any party”.
Should supporters be cautious?
There have been sporadic reports of protests in Honduras after the counting of votes. However, none have been reported to get serious.
There is no escaping the right-wing influence in the country, with many US-backed violent anti-drugs efforts being carried out by Honduran security forces.
This has increased the role of the powerful gangs in Honduras.

What about the left?
Former members of President Manuel Zelaya’s administration say that the most serious threat to democracy will come from the new electoral council, which is dominated by right-wing candidates.
It has put in place a power-sharing arrangement with a relative of former President Zelaya.
