Jordan Bardella, the party's president, denounced the police action as harassment and a threat to democracy and political pluralism in France. Approximately 20 armed officers participated in the raid, during which extensive documentation, including emails and financial records, was confiscated. Bardella criticized the justice system, stating that never before had an opposition party faced such relentless scrutiny under the current republic.

The catalyst for this investigation was a series of anonymous alerts regarding the funding of the National Rally's election campaigns. The prosecutor's office is specifically examining whether the party or its candidates secured illegal loans from private sources or engaged in fraudulent invoicing practices for campaign expenditures. Although French law permits private loans to political entities, stricter regulations govern the conditions under which such financing can occur.

As the leading opposition party in the National Assembly since the last snap elections, the National Rally, which has been associated with anti-immigrant rhetoric, has made substantial electoral gains. Its former leader, Marine Le Pen, has unsuccessfully run against President Emmanuel Macron in the past two presidential contests, signaling the party's escalating prominence in French politics.

The investigation remains ongoing, with no charges filed yet, and much anticipation surrounds the resulting implications for the National Rally and its leadership.
