His father was then transferred back to Andalusia, taking the family to Fuengirola; he had a brief time back in La Rinconada due to his mother's illness. He graduated in Economic and Business Sciences from the University of Málaga,^[1] where he began to affiliate with left-wing politics, joining the Spanish Socialist Workers' Party (PSOE) in 1983. He was elected the same year to the city council in La Rinconada, where he remained for eight years.^[2]
