Spanish police discovered more than 100 pieces of jewellery hidden in a safe during a raid of former Prime Minister José Luis Rodríguez Zapatero's office [1].

The discovery intensifies a high-profile investigation into alleged corruption and irregularities involving state aid. The case centers on the Plus Ultra Líneas Aéreas airline and the role of influential figures in securing government funds.

Agents from the Unidad de Delincuencia Económica y Fiscal (UDEF) carried out the registration on Tuesday, May 19, 2026 [1], [2]. The operation began shortly after 8 a.m. [1]. Reports said agents entered the Madrid office with the assistance of Zapatero's secretary [1].

The raid is part of the broader Plus Ultra case. Zapatero has been indicted for alleged irregularities related to state aid provided to the airline in 2021 [2], [3]. Investigators are examining whether the former leader used his influence to facilitate the aid package.

While the UDEF has not yet detailed the origin of the jewellery found in the safe, the discovery occurred as police analyze the former prime minister's activities [1]. Police said Zapatero's residence and office were key spaces for the coordination of the Plus Ultra plot [3].

The investigation remains active as authorities seek to determine if the recovered assets are linked to the alleged irregularities of the airline case [2], [3].

UDEF agents discovered more than 100 pieces of jewellery hidden in a safe.

The discovery of undisclosed luxury assets during a corruption probe typically increases legal pressure on a defendant to explain the source of funds. In the context of the Plus Ultra case, these findings may provide the UDEF with evidence of illicit payments or undisclosed wealth that correlates with the timing of the 2021 state aid irregularities.
