Governing party candidate Juan Manuel Santos has won the final round of the presidential elections in Colombia.
With results from more than three quarters of the polling stations counted, Mr Santos was ahead of his rival Green Party candidate Antanas Mockus by more than 40 points.
With three-quarters of voting stations reporting, Mr Santos had 69% percent of the votes.
Antanas Mockus won 28% of the votes.
Opinion polls conducted ahead of the election had predicted a win for Mr Santos, who had also led in the first round.
Mr Santos, an ex-defence minister, has backed outgoing President Alvaro Uribe's tough line on security.
His opponent, Antanas Mockus, a former mayor of Bogota, said he wanted to end the corruption scandals that swirled around the Uribe government.
Despite tight security measures across the country, 10 members of the security forces were killed in rebel attacks on polling day.
But the BBC's Jeremy McDermott in Bogota says the level of violence was much lower than in previous presidential elections, when Colombia's rebel groups managed to seriously disrupt voting with attacks across the country.
Mr Santos, standing for Mr Uribe's Social National Unity Party, has portrayed himself as the heir to the outgoing president, whose approval ratings remain as high as 60% even after eight years in office.
Mr Uribe had hoped to seek a third term himself, but proposals to change the country's constitution to allow him to stand again were ruled illegal by Colombia's Constitutional Court.
Mr Uribe's supporters transferred their backing to Mr Santos, giving him a broad support base.
Nonetheless, Mr Santos failed to reach the 50% threshold for an outright win in the first round on 30 May, and so had to face Mr Mockus in this second round of voting.
