Argentina's right-wing congressman and economist, Javier Milei, has won the country's presidential runoff.
The voting took place on Sunday amid economic turmoil in the country, including soaring inflation.
The electoral authority says with 98 percent of the votes counted, Milei had 55.7 percent, while Economy Minister Sergio Massa from the ruling center-left party got 44.2 percent.
Milei has drawn comparisons with former US President Donald Trump for making radical statements. They include scrapping Argentina's central bank and changing its currency from the peso to the US dollar to stabilize prices.
Milei favors stronger US ties. He says he will review Argentina's relations with countries such as China.
