In 1977, in the first Spanish elections after the end of Francoist Spain, he became senator for Barcelona as an independent candidate. In 1979, he was a candidate for the Spanish Congress of Deputies in a coalition known as Left Bloc of National Freedom (Bloc d'Esquerra d'Alliberament Nacional or BEAN). This reinvigorated the spirit of the former Assembly of Catalonia, of which he also was one of the main promoters. Later on, BEAN presented candidates in the 1980 Catalan Parliament elections; but, in both cases, it did not obtain any representation.
