[3] Until 2011, all elections with the exception of 1995 produced an absolute majority for the Spanish Socialist Workers' Party (PSOE).

A PSOE-led administration was formed after the 2015 elections, and the PSOE regained its absolute majority in 2019 and held it in 2023.

The electoral alliance ended in 1986 and the AP and UV contested the 1987 local elections separately.

In 1989 the AP merged with the PDP and UL to form the current People's Party.
