A prestigious group of Catalan scientists announced its support for the pro-independence coalition Junts pel Sí (Together for Yes), which it considers the "best option" to ensure the growth of the country’s research system. The manifesto is signed by 11 personalities, including Jordi Galí, Joan Massagué, Bonaventura Clotet, Joan Ramon Resina, Josep Maria Gatell, Manel Esteller, Josep Maria Llovet, Xavier Estivill, Ramon Brugada, Jaume Bertranpetit, and Carles Boix. The document takes issue with the Spanish government’s policies and warns that Catalonia cannot take "the great leap forward towards the generation of economic progress" without the "structures" of an independent state. "The Catalan Parliamentary elections on September 27 represent a great opportunity for science in Catalonia. In view of the situation described, the undersigned declare our support for the candidacy of Together for Yes, which we believe to be the best option to maintain the consensus developed over so many years", they concluded.
