Milei, a self-styled right-wing libertarian, also lashed out at  Sánchez’s deals with Basque and Catalan separatists, saying the Spanish prime minister had “endangered the unity of the Kingdom, making pacts with separatists and leading to the dissolution of Spain.”

He added that illegal immigration in Spain was threatening women’s safety.

The Spanish government on Saturday categorically rejected Milei’s claims, saying they “do not correspond to the relations of two brother countries and peoples.”

Relations between Spain and Argentina have chilled since Milei’s election last in December. The Argentine leader had publicly supported Spain’s right-wing opposition party Vox.
