Tens of thousands of marchers take to streets as schools and businesses close in protest at president’s extreme legislation

Argentine demonstrators have staged their biggest-yet show of opposition to Javier Milei’s radical attempt to reshape the South American country with a nationwide strike that shuttered schools and businesses, grounded hundreds of flights, and saw tens of thousands of marchers hit the streets.

Milei, a boisterous celebrity economist nicknamed “El Loco” (the Madman), became president in December vowing to free Argentina from decades of “decadence and decline” with his libertarian ideas. Since then, the far-right politician has moved speedily to implement what the former Ukip leader Nigel Farage recently called “Thatcherism on steroids” – first with a far-reaching emergency decree; then with a mega-reform bill known as the “omnibus law”.
