In Burgos, a breakway party, Independent Solution (SI), formed by the incumbent mayor of its capital city José María Peña San Martín, obtained one seat in the regional Cortes.

As a result of the election, the support of PDP and SI procurators and the decisive abstention of the CDS, AP candidate José María Aznar was able to become president of the Junta of Castile and León, replacing Socialist José Constantino Nalda and starting an uninterrupted stay of over three decades in power for AP and its successor, the People's Party (PP).

Aznar's presidency would last until 1989, when he would resign to Jesús Posada in order to become the PP's national leader and, in 1996, prime minister of Spain.

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

All members of the Cortes of Castile and León 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.

[3][4][6] The Cortes of Castile and León 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.
