Madrid, 4 Apr (RHC) The General Attorney's Office of Spain is  investigating the possible involvement of companies and citizens in illegal transactions within the Panama Papers' case.

Prosecution sources announced the beginning of the inquiry, together with Agencia Tributaria, because of the documents disclosed through a huge leak that will probably involve many people.

Pilar de Borbón, sister of King Emeritus Juan Carlos, film director Pedro Almodóvar and members of the Domecq family, are some of the Spaniards listed as linked to the international scandal of the Panama Papers.

The investigators are trying to establish hypothetical money laundering, with aid of the law firm Mossack-Fonseca, that specializes in creating societies with fiscal advantages.
