The election saw the electoral collapse of the Democratic and Social Centre (CDS), which fell below the 5% threshold and lost all their 17 seats.

Consequently, Joaquín Leguina from the Spanish Socialist Workers' Party (PSOE) was re-elected President for a third term in office thanks to the support of United Left (IU).

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

All members of the Assembly of Madrid 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 regionally.

[2][3][4] After legal amendments in 1990, the president was granted the prerogative to dissolve the Assembly of Madrid and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year had elapsed since the previous one.

The ruling PSOE was initially able to hold on to power and have Joaquín Leguina re-elected President thanks to CDS' abstention, but nonetheless the government's majority remained precarious.

However, he abstained, and the United Left members blocked the motion alongside PSOE, resulting in the vote failing.

Investiture processes to elect the President of the Community of Madrid required for an absolute majority—more than half the votes cast—to be obtained in the first ballot.
