The PSC and Units per Avançar are the best-matched couple in Catalan politics. The alliance between these two political forces began in 2017, when the socialists started to want to get closer to the skeptical nationalists (or even scared) with the break-away approach of independence and who had already begun to miss CiU. The leader of Units, Ramon Espadaler, embodied this profile: former minister in the government of Jordi Pujol and Artur Mas, he launched in June of that year what he then defined as a "Catalanist" and Christian democratic platform that, in Catalonia in the months leading up to 1-O, advocated for dialogue with Spain with the backing of former members of Unió. The then first secretary of the PSC, Miquel Iceta, did not hesitate to make them an offer to run together in the elections. The wedding was officiated in a hotel in front of the PSC headquarters on Nicaragua street under the slogan "Alliance for common sense and Catalanism" and was the prelude to the move to recruit centrist profiles that Salvador Illa deployed when he landed in the Generalitat. However, and almost ten years after that understanding, Units does not renounce to make its mark to avoid being swallowed by the socialist tide, now that the PSC governs at all four levels of administration.
