Panamanians are voting in a general election which has been overshadowed by the disqualification of the man who was leading in the polls.
Ex-President Ricardo Martinelli was the favourite to win until he was banned from running after being found guilty of money laundering.
His replacement on the ballot, José Raúl Mulino, is leading in the polls.
Whoever wins most of the votes in this round will be declared president and sworn in on 1 July.
There are a total of eight candidates competing for the presidency, and voters will also choose members of Panama’s national assembly. As presidents cannot serve two consecutive terms, the incumbent, Laurentino “Nito” Cortizo, will not stand for re-election.
Opinion polls put Mr Mulino in the lead. The 64-year-old lawyer from the Realizando Metas (Achieving Goals) party was Mr Martinelli’s running mate.
But after Mr Martinelli was sentenced to almost 11 years in prison for money laundering, Mr Mulino joined the race for president.
However, Mr Mulino’s candidacy has also faced legal challenges.
Panama’s top court was asked to decide whether the fact that Mr Mulino was not chosen by his party in the customary primary election invalidated his candidacy.
