Francesc de Carreras

[2] He left the PSUC in 1986 over concerns the party line was drifting towards Nationalist stances.

[3] He was a prominent member of the Foro Babel, a civil forum created to denounce the language policy enforced by the Catalan regional governments presided by Jordi Pujol.

[8] Tenured professor in possession of a Chair in Constitutional Law at the Autonomous University of Barcelona (UAB), he retired in September 2013.

[9] Elected as numerary member of the Royal Academy of Moral and Political Sciences in January 2015,[10] he took possession of the medal number 27 on 15 November 2016, covering the vacant left by Manuel Jiménez de Parga (his PhD thesis supervisor), reading a speech titled Ensayos sobre el federalismo ("Essays about the Federalism").

[11][12] Carreras has been a critic of the rightwing drift of Cs driven by party leader Albert Rivera (his former pupil), warning in 2019 that the later would be "putting alleged party interests ahead of the interests of Spain" and that Rivera had turned into a "capricious teenager".
