‘El Loco’ wins landslide victory in Argentina that experts say shows scale of frustration with Peronist status quo

• What does Argentina’s new president stand for?

Luminaries of the global far right are in raptures over Javier Milei’s thumping election victory in Argentina which experts predict will turn Buenos Aires into a new stomping ground for the populist radical right.

Donald Trump and Jair Bolsonaro led the merrymaking after their Argentinian ally trounced his rival, the Peronist finance minister Sergio Massa, by nearly 3 million votes in Sunday’s presidential election. The former US president predicted Milei would “truly make Argentina great again” while Brazil’s ex-president applauded a victory for “honesty, progress and freedom”. Bolsonarista and Mileísta activists predicted Milei’s win would be the first in a trio of rightwing conquests that would see Trump and Bolsonaro reclaim power in 2024 and 2026.

Victory for TV celebrity-turned politician catapults South America’s second-largest economy into an unpredictable future

Good morning. Today we’re heading to Buenos Aires, where left-wing and centrist Argentinians have taken to the streets celebrating that the country may be about to avoid electing a far-right president described by some as a mashup of Donald Trump, Boris Johnson and The X-Men’s Wolverine – who describes himself as “anarcho-capitalist”.

Until the results of the first round of Argentina’s presidential election trickled out early yesterday morning, the polls and the pundits had predicted that eccentric far-right populist Javier Milei – whose signature mop of untamed hair and long sideburns is a professionally designed homage to Elvis and the aforementioned superhero – would probably become the country’s next president.

Soft-spoken Sergio Massa’s campaigning strategy pays off while voters seem to pull back from libertarian rival – but who will win the runoff?

After a disastrous showing in Argentina’s open primaries in August, Argentina’s Peronist party made a resounding comeback this week. In the latest chapter in a rollercoaster presidential election, the soft-spoken economy minister, Sergio Massa, snatched what seemed like a sure victory from the jaws of the libertarian Javier Milei, winning 36.6% of the vote against only 29.9% for Milei.

The broad margin was still not enough to avoid a runoff on 19 November between the two most dissimilar contenders imaginable. Although beset by soaring price inflation and a 40% poverty rate, Massa trounced Milei, whose promise to dollarize the economy and legalize the organ trade had catapulted him to surprise victory in August.
