It is often said that in politics everything has been seen: unnatural alliances, sudden changes of position or leaders who move to another party. In fact, moving from one party to another is not exceptional in Catalonia. With the 'Procés', leaders from the PSC or ICV joined ERC, representatives from Cs joined the PP with the decline of the orange party, and now Junts officials are moving to Aliança. What is not usual are the changes of allegiance between parties located at opposite ends of the ideological spectrum.
