Juan Orlando Hernández has been declared the winner of last month’s fiercely disputed presidential election in Honduras after a partial recount.
Earlier results triggered deadly street violence and protests.
Mr Hernández’s main opposition Salvador Nasralla accuses electoral authorities of vote-rigging.
The Organisation of American States (OAS) had urged authorities not to announce a final result and said “serious questions” persisted.
But the country’s electoral tribunal announced in a televised address on Sunday that the incumbent President Hernández won by 1.53% of the vote.
Authorities had initially said Mr Nasralla had a five-point lead on the morning after the election on 25 November.
That gap began to close after a computer problem was reported at the vote-tallying centre in the capital, Tegucigalpa.
