The candidate for the governing conservative Sovereign People's Party, Laura Fernández, has won the presidential election in Costa Rica.

With more than 88% of the votes counted, Fernández had over 48% of the votes, far ahead of the second-placed centrist candidate, Álvaro Ramos, who conceded defeat.

Fernández ran on a promise to deepen the tough-on-crime approach of the outgoing President Rodrigo Chaves, who had handpicked her as his successor.

Voters had said they were concerned about a surge in drug-related violence in the Central American country.

The size of her vote share - which exceeded the 40% needed to win outright in the first round - means that there is no need for a run-off.
