As an autonomous community of Spain, Aragon has an elected regional parliament (Spanish: Cortes de Aragón, Aragonese: Cortz d’Aragón, Catalan: Corts d’Aragó) with 67 seats. It meets in the Aljafería, a Moorish palace in the capital city, Zaragoza. The Parliament chooses a President for the Diputación General de Aragón or Aragon Government, for a four-year term. The current president (since July 2015) is Javier Lambán of the PSOE. Nationally, Aragon elects 13 Deputies and 14 Senators to the Cortes Generales.

In addition to the Spanish-based political parties, there are a number of Aragón-based parties, such as the Chunta Aragonesista, a left-wing Aragonese nationalist party, and the Aragonese Party, more conservative. Chunta Aragonesista had a seat in Spain’s national Congress of Deputies from 2000 to 2008, while the centrist Aragonese Party has three national senators, who are in coalition with the ruling People’s Party.

In a 2011 regional government survey, 47.6% of the population wanted greater autonomy for Aragon, while 35.2% were satisfied with its current level of autonomy. A total of 6% wanted an end to autonomy and 3.2% wanted full independence.
