He is also in charge of the executive coordination for the re-foundation of Ciudadanos and of building a stronger relationship with liberal parties around the EU.

[13] In 2024, as Secretary General of Ciudadanos, he defended before his party colleagues that, given the political situation Spain was facing, the best option for the liberal formation was to form an electoral coalition with the Partido Popular for the 2024 Catalan and European elections.

Following the coalition's failure, and consistent with his ideal of not dividing the center and right-wing vote against Pedro Sánchez, Adrián resigned from all his positions in Ciudadanos.

Adrián Vázquez ran as number 10 on the PP list in those elections and was re-elected as a Member of the European Parliament in June 2024.
