Spanish police raided the headquarters of the ruling Socialist Party today in a fresh corruption scandal blow to Prime Minister Pedro Sanchez, whose government is also facing fierce backlash over plans to legalise 500,000 migrants.The Civil Guard said officers were searching the party's central Madrid offices under judicial orders linked to an ongoing probe into alleged financial wrongdoing involving a former Socialist Party member connected to a state-run company. The raid is the latest blow for Sanchez and his Socialist government, which has been rocked by a string of corruption allegations involving senior figures close to the prime minister.Just last week a different court said it was investigating former prime minister Jose Luis Rodriguez Zapatero for alleged influence peddling and other possible crimes tied to a government airline bailout. He has denied any wrongdoing.Sanchez's wife and brother are being probed over allegations of influence peddling, which both have denied.And, most damning for the Socialists, a former minister under Sanchez and a senior party official are both being investigated on allegations they played a part in a kickback ring that started during the Covid-19 pandemic, which they have denied. Sanchez, prime minister since 2018, has called the cases against his family a 'smear campaign'.But the corruption case against his former cohorts led him to ask the nation for 'forgiveness' in 2025. Spanish police raided the headquarters of the ruling Socialist Party today in a fresh corruption scandal blow to Prime Minister Pedro Sanchez (pictured), whose government is also facing fierce backlash over plans to legalise 500,000 migrants Members of the media gather outside the ruling Spanish Socialist Party - PSOE headquarters while agents from the UCO, the Civil Guard unit specializing in complex and sensitive investigations, raid the facilities in Madrid, on May 27, 2026The latest scandal comes as Sanchez is already facing fierce criticism over his government's controversial migrant regularisation scheme, which aims to give legal status to around 500,000 undocumented migrants. Huge queues have formed in cities across Spain after the government approved plans to legalise the migrants.The applications opened after Spain's Socialist government rubber-stamped the initiative at a cabinet meeting, triggering long waits at immigration offices across the country. Spanish police have warned that Islamist terrorists could exploit the mass migrant legalisation programme as reports of lost passports and identity documents surged among applicants.An internal memo from the National Police's General Commissariat for Immigration and Borders, seen by Spanish outlet La Gaceta, said complaints over missing documents had risen sharply among migrants seeking to benefit from the scheme.According to the document, the biggest increases in lost document reports were recorded among Pakistani, Algerian and Moroccan nationals.Police said the nationalities most frequently linked to the missing document complaints overlapped with profiles that have previously appeared in investigations related to Islamist extremism.The memo ordered officers to intensify identity and background checks because of what it described as the difficulty, and in some cases impossibility, of reliably confirming applicants' true identities.The controversy is unfolding while Spain remains under its long-standing level four anti-terrorism alert, one step below the maximum.Official figures from Spain's Interior Ministry show more than 100 arrests linked to jihadism were carried out in 2025, marking the highest annual total since the 2004 Madrid train bombings.
