Maldives opposition candidate declares victory in high-stakes presidential election
Solih said he won with a 16% margin after 92% of the votes were accounted for, according to Reuters.
"The will of people has spoken; and it has spoken decisively for change," Solih said, according to state broadcaster PSM News.
Incumbent President Abdulla Yameen, who has been accused of cracking down on dissent and jailing opposition leaders, has not officially conceded.
In a televised press conference, Solih said his priority is to unite the country after such a contested election, and called upon the incumbent to ensure a peaceful political transition.
Transparency Maldives, an anti-corruption nongovernmental organization, acted as an observer during the elections and said its results also indicated Solih had won.
"Our quick count results indicate that Ibrahim Mohamed Solih has won the 2018 presidential election by a decisive margin. We call on all stakeholders to maintain an environment conducive for a peaceful transfer of power," the organization posted on its Twitter account.
Former Maldives President Mohamed Nasheed, who governed the country from 2008-2012, congratulated Solih in a message on his official Twitter account.
"You have done an extremely good service not only to the people of Maldives, but also to freedom loving people everywhere. Democracy is a historical inevitability," Nasheed wrote.
