As a member of the Spanish Socialist Workers' Party (PSOE), he was the first democratically elected mayor of Palma de Mallorca, in office from 1979 to 1991.
Born in Palma de Mallorca, Aguiló took scholarships to complete his Spanish Baccalaureate, while working in a photography workshop and as an electrician.
[5] Aguiló said in 2009 that the PSOE establishment prevented him from rising in their ranks, by saying in the late 1980s that he was too young to be a member of the Congress of Deputies and impeding his attempt to run for general secretary of the Socialist Party of the Balearic Islands.
[6] Aguiló quit the PSOE in 2001 due to disputes over the professionalisation of politics, the GAL scandal in the Basque Country, and the support of nationalist parties.
[8] During his time as mayor, Aguiló faced antisemitism as his surname was one of 15 in the community of Xuetes, an endogamic group of formerly Jewish conversos in Mallorca.
