BUENOS AIRES - Conservative opposition candidate Mauricio Macri comfortably won Argentina's presidential election on Sunday after promising business-friendly reforms to spur investment in the struggling economy.
Macri's supporters swarmed to the Obelisk in the heart of Buenos Aires' theatre district for a giant street party as subdued ruling party candidate Daniel Scioli conceded defeat.
Argentina's election body said Macri had 53 percent of votes and Scioli had 47 percent with returns in from three-quarters of polling stations. Three exit polls also pointed toward a Macri victory.
In a sign of Argentines' weariness with a spluttering economy, rising crime and corruption, Macri had gone into the run-off election with a comfortable lead in opinion polls over Scioli, the candidate of outgoing President Cristina Fernandez.
