The Socialist Party (PSOE) has regained control of Jaén's city council through a controversial motion of no confidence, ousting the Popular Party (PP) mayor, Agustín González.
Julio Millán, the new mayor, secured the position with the support of Jaén Merece Más, a local party, in a deal reportedly backed by Spain's Ministry of Finance.
The agreement includes measures to address the city's significant debt and promises of new investments.
This political shift marks a symbolic blow to the PP's dominance in Andalusia, where it had controlled all eight provincial capitals.
The PSOE aims to use this victory as a stepping stone to rebuild its influence in the region, a former stronghold.
Millán defended the motion as a democratic tool, countering accusations of political maneuvering by the PP.
The move has sparked debate over its implications for Andalusian and national politics.
