A member of extreme-left organizations and participant in Barcelona's counter-cultural scene in the 1970s, he experienced a radical rightward drift, eventually becoming a journalistic guru for a right-wing audience.

[8] Literature and language teacher at a high school in Santa Coloma de Gramanet and one of the promoters of the so-called "Manifesto of the 2,300" [es] denouncing the alleged "intention to make Catalan the only official language of Catalonia", he was kidnapped by Terra Lliure in 1981; after being gagged and shot at the leg by Pere Bascompte [es] in a wasteland in Esplugues de Llobregat, Losantos was left abandoned and tied to a tree by the kidnappers.

[12] He worked as a literature teacher at the Instituto Lope de Vega high school in the Spanish capital.

After a year in Miami, he returned to Spain and took charge of La Linterna, a night programme on COPE radio.

With La Mañana he became one of the most listened-to radio talk show hosts in Spain until he parted ways in July 2009.

[13] In 2000, together with the likes of Javier Rubio Navarro, José María Marco, Alberto Recarte, Carlos Rodríguez Braun and Pedro Schwartz, Losantos helped to create Libertad Digital, a markedly partisan right-leaning and anti-socialist online newspaper.

Including a quarrel filed by Alberto Ruiz-Gallardón,[15][n. 2] and being legally prompted, along with his employers COPE, to pay compensation of 60,000 euros to Esquerra Republicana de Catalunya.

[18][19] In 2009, after the discomfort that Losantos' outspoken and uncompromising editorial line was creating in the COPE (deeply critical of the former Spanish premier Zapatero, but, somewhat surprisingly for Spain's partisan politics, equally critical of the conservative opposition, which he chastises as being bland and lacking a real alternative project), he did not accept the new role he was offered by this radio station and announced he was moving, among others, to create his own radio station, esRadio, to be launched in September of that same year.
