Aparicio was the first democratically elected mayor of Málaga in 1979. Though his party needed to form a coalition with the Communist Party and the Andalusian Party in that year, he was re-elected with absolute majorities in 1983, 1987 and 1991. In 1995, he left office as Celia Villalobos of the People's Party was elected.[1][2] His main priority at the beginning of democracy in Spain was to improve the lives of people in Málaga's outskirts, where roads were not paved and many homes lacked electricity and running water.[1][2] During his mandate, the city founded the Fundación Picasso which bought Pablo Picasso's birthplace and opened it to the public, while the Teatro Cervantes [es] was opened and the Málaga Symphony Orchestra was initiated.[2]
Aparicio exercised every morning to manage his diabetes, hypertension and excess weight. At the end of his daily routine at a local sports centre on 25 September 2014, he died suddenly of heart failure at the age of 71. The city council suspended its work for the day upon hearing the news, and declared two days of mourning.[1] His funeral was held on 2 October.[4]
A prize for journalism in Málaga was named after Aparicio and first awarded in 2017.[5]
