Centre-left candidate Laurentino Cortizo has been declared the winner of Panama’s presidential election.

In an unexpectedly close race, Mr Cortizo finished two percentage points ahead of his centre-right rival, Rómulo Roux.

Mr Roux has yet to concede, citing reports of voting irregularities.

The elections have been dominated by pledges to fight corruption and to tackle Panama’s image as a money-laundering country.

The country’s electoral tribunal says 95% of ballots have been counted, with Mr Cortizo winning 33% of votes, followed by Mr Roux with 33%.
