The former president of the Regional Government of Andalusia Rafael Escuredo had been replaced in the post by José Rodríguez de la Borbolla in March 1984.

[1][2] The election saw Rodríguez de la Borbolla's PSOE–A renew its mandate, albeit with a slightly reduced majority.

In contrast, the left-wing United Left–Assembly for Andalusia (IU–CA), the Communist Party of Spain (PCE)-led coalition formed in Spain in the aftermath of the NATO membership referendum held on 12 March, achieved a major electoral breakthrough under the candidacy of former Córdoba mayor Julio Anguita, scoring almost 18% of the share, 19 seats and coming within a three-point margin of becoming the most voted political party in the Córdoba constituency.

[3] Voting for the Parliament was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Andalusia and in full enjoyment of their political rights.

The 109 members of the Parliament of Andalusia were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which included blank ballots—being applied in each constituency.
