Justice conducted several investigations into Juan Carlos’ money flows and possessions. This included an investigation into the involvement of the former king in the sale of contracts for the construction of the ‘high-speed train of the desert’ in Saudi Arabia. He would have received commission for that.
The cases against Juan Carlos have been dropped for several reasons, including the lack of incriminating evidence and the immunity of the head of state.
Juan Carlos, 84, ruled Spain from 1975 to 2014. He retired as head of state for health reasons, but officially retained his title. Due to the allegations against him, he moved to the United Arab Emirates in 2020.
