swept the
province of Valencia on 29 October 2024, with the poor
crisis management by
Carlos Mazón's administration being perceived as contributing to the high death toll of 229. The
2023 regional election had seen the "
Botànic Agreement" of left-of-centre parties being ousted from power by an alliance of the
People's Party (PP) and the
far-right Vox party, which formed a
coalition government under regional PP leader
Carlos Mazón. Negotiations for forming the new
Mazón's government coincided with the
electoral campaign of the
2023 Spanish general election, a factor which was said to contribute to the PP's electoral disappointment by evidencing the party's willingness to allow the far-right into government despite public pledges to the contrary. This coalition lasted until July 2024, when Vox's national leader
Santiago Abascal forced the break up of all PP–Vox regional governments over a controversy regarding the nationwide distribution of
unaccompanied migrant minors among the autonomous communities, leading Mazón to immediately dismiss all Vox ministers in his cabinet. Mazón's tenure was overshadowed by the
29 October 2024 floods across the
province of Valencia, caused by
torrential rains that brought over a year's worth of
precipitation, resulting in one of the deadliest natural disasters in Spanish history with 237 deaths—229 in the province of Valencia alone—and substantial property damage. The
Valencian government was criticized for its lack of
emergency preparedness and poor
disaster response, with Mazón initially downplaying the scale of the floods, then remaining unreachable and his emergency services paralyzed during the most critical hours of the crisis, a late sending of
emergency alerts to the endangered population—which arrived when hundreds were already trapped or dying—and the apparent inability of regional authorities to cooperate adequately with the
national government. A judicial probe for
reckless homicide over alleged
negligence in the
management of the crisis was opened on several high-ranking regional officers, including the regional minister responsible for emergency services at the time of the floods, while Mazón's popularity plummeted in opinion polls amid his constant changes of story about his whereabouts during the height of the disaster. Support from the PP's national leadership under
Alberto Núñez Feijóo helped Mazón survive calls for his resignation, but his political position remained weak. Public outrage at him was evidenced at the
memorial ceremony held on the first anniversary of the tragedy, during which he was jeered and insulted by family members of victims. Added to new evidence hinting at a possible
omission of duties while the floods devastated entire towns, and with the judicial investigation closing in on him, Mazón allegedly lost his party's support. With his political demise seeming imminent, the PP descended into chaos on 1–2 November 2025 as the national and regional leaderships vyed for controlling his succession. Mazón himself considered resigning and challenged Feijóo by threatening a snap election, while the party crisis deepened due to difficulties in agreeing on a successor and on whether Mazón would be able to retain
immunity from judicial prosecution. The latter announced his resignation as regional president on 3 November—claiming that he could not "go on anymore"—pending a negotiation with Vox to elect an interim replacement. The PP selected
Juanfran Pérez Llorca to succeed Mazón in the regional presidency, with Vox supporting his investiture on 27 November in exchange for concessions on environmentalism, education, migration and language policy. ==Overview==
