As a result of the previous election, the Spanish Socialist Workers' Party of Andalusia (PSOE–A) was able to retain power after obtaining confidence and supply support from Citizens (Cs), with such alliance enduring President Susana Díaz's defeat in the 2017 PSOE leadership election. The PSOE–Cs agreement broke up in September 2018 after Cs withdrew their support from Díaz's government, prompting Díaz to announce the Parliament's dissolution on 8 October and call a snap election for 2 December 2018.
