Spain's Prime Minister Pedro Sánchez leads a minority PSOE government that depends on support from left-wing, Catalan, and Basque parties in Congress, creating ongoing vulnerability to coalition fractures or no-confidence motions. His recent foreign policy decisions, including withdrawing Spain's ambassador to Israel, closing airspace to U.S. military flights involved in strikes on Iran, and rejecting involvement in related operations, have strengthened his domestic standing by appealing to voters opposed to the actions. Sánchez has publicly committed to remaining in office despite ongoing judicial scrutiny of his wife over alleged influence peddling and persistent criticism over housing affordability and prior corruption cases. Scheduled events such as the April 2026 Progressive Mobilization summit in Barcelona and potential budget negotiations later in the year could further shape parliamentary dynamics and test the government's stability.
