Argentina elected right-wing libertarian Javier Milei as its new president on Sunday, rolling the dice on a political outsider with libertarian views to fix an economy battered by triple-digit inflation, a looming recession and rising poverty. Milei, who rode a wave of voter anger with the political mainstream, won by a wider-than-expected margin. He landed some 56 per cent of the vote versus just over 44 per cent for his rival, Peronist Economy Minister Sergio Massa, who conceded.
