Political Corruption and the End of two-party system after the May 2015 Spanish Regional Elections

The autonomous elections held on 25 May 2015 took place simultaneously in 13 of the 17 Spanish autonomous communities (CCAA), leading to the most profound change in the autonomous party system seen in Spain in the last 20 years. A significant number of Spanish citizens hold the two main parties—the PP and the PSOE—responsible for being unable to solve their economic problems and for having pursued their austerity policies and containment of social expenditure to the extent of giving rise to the greatest inequality experienced in Spanish society in history. Furthermore, and as important as the economic crisis, support for the new parties, Podemos and Ciudadanos, has been linked to the emergence in Spanish public debate of party regeneration and the corruption scandals that tainted the main parties and most institutions in the years prior to the elections on 25 May 2015.
