The main election winner was the centrist Democratic and Social Centre (CDS), a party led by the former Spanish Prime Minister Adolfo Suarez, which entered the Assembly for the first with 8 seats and 12% of the vote, becoming the only party within the Assembly that made gains, as all others (including regionalist United Extremadura (EU)) lost votes.

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

The 65 members of the Assembly of Extremadura were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of five percent of valid votes—which included blank ballots—being applied in each constituency.

[1][2][3] The Assembly of Extremadura could not be dissolved before the date of expiry of parliament except in the event of an investiture process failing to elect a regional president within a two-month period from the first ballot.
