‘El Jefe’: is Karina Milei the power behind Argentina’s presidential throne?

Javier Milei swept aside an anti-nepotism law to appoint his sister to a high-ranking position - but who is she?

When Javier Milei first walked into Argentina's presidential palace earlier this month, the radical libertarian leader was not accompanied by his vice-president, Victoria Villarruel, nor his partner, the actor Fatima Florez.

Milei's escort at this key political moment was a woman who many analysts describe as the true power behind his throne: his sister, Karina.
