Argentina has elected Javier Milei, a self-styled radical outsider and former TV pundit, to be their next president.
He won 56% of the vote, compared to the 44% won by Sergio Massa of the ruling left wing Peronist party.
Milei rode a wave of frustration to the polls - declaring that drastic changes are needed in the country, which has been ravaged by debt and inflation.
Addressing supporters in Buenos Aires, Javier Milei said he would plot a radically different course and cut back on what he called the "omni-present state" that has brought only suffering to the majority.
Among his promises is to do away with the central bank and replace the peso with the US dollar.
