"They treated him like a villain, a negationist, a 'substance abuser', an authoritarian, an anti-democrat and a 'very bad' person. I hope that at some point they will reflect and sincerely apologize", said Adorni on the social network X (formerly Twitter).

Also another spokesperson for the presidency of Argentina, Javier Lanari, had accused the Minister of Transport of Spain, Óscar Puente, of insulting Milei, by describing him as "a drug addict", earlier this month.

"He was not the only one: the Spanish Minister of Science [Diana Morant] called Milei a 'negationist' and said that he 'attacks democracy'. But the one who puts relations at risk and should apologize is Milei...", Lanari said ironically.

On Saturday, the Government of Spain had withdrawn the country's ambassador in Buenos Aires because of statements by Milei, which Madrid considered as insults to the leader of the executive, Pedro Sánchez.

Hours before, Milei referred, in Madrid, at a convention of the far-right party Vox, to the "damned and cancerous socialism", before adding: "What a bunch of people screwed to power. Even when you have a corrupt woman, you get dirty and take five days to think about it".

The socialist Pedro Sánchez said at the end of April that he was considering resigning, invoking attacks on his family, especially his wife, based on disinformation campaigns. After five days of reflection, he decided to remain in office.

"Mr. Milei, with his behavior, has brought relations between Spain and Argentina to the most serious moment in our recent history", said on Saturday the Spanish Minister of Foreign Affairs, José Manuel Albares, in a statement in which he announced that he had called to Madrid the ambassador María Jesús Alonso, "for consultations", for a period 'sine die'.

"Spain also demands public apologies from Mr. Milei. If these apologies are not produced, we will take the measures that we consider appropriate to defend our sovereignty and our dignity", added Albares, without giving further details.

The minister considered that Milei's words "go beyond any type of political and ideological difference" and "are unprecedented in the history of international relations and even less in the history of relations between two countries and two peoples united by strong ties".

Milei arrived in Madrid on Friday and returned to Argentina on Sunday, after participating in the Vox convention.

It was the first trip he made to Spain after taking office as President, but he did not meet with any authorities in the country.

The Argentine Government explained last week that Milei intends to return to Spain in June and there he will request official hearings.
