Camilo Villarino Marzo (Zaragoza, 11 April 1964) is a Spanish diplomat and jurist who serves as Private Secretary to the King since 19 February 2024.

[5] Between 2008 and 2013 he held the position of counselor for Transatlantic relations and security and defense affairs at the Spanish Embassy in the United States and, between 2013 and 2017, he was deputy to the ambassador of Spain to Morocco.

[citation needed] In June 2017, the conservative foreign minister Alfonso Dastis appointed him as his chief of staff, a position he held with two of his successors, the socialists Josep Borrell and Arancha González Laya.

[7] This controversial change of opinion had nothing to do, according to the minister, with the fact that Villarino was then accused of the so-called "Gali Case", for illegally allowing the leader of the Polisario Front, Brahim Ghali, to enter Spain.

[9] After this, he joined the European External Action Service[10] and, shortly after, at the end of 2022 he was appointed as Head of the Cabinet of the High Representative of the Union for Foreign Affairs and Security Policy, Josep Borrell.
