According to the media Eldiario.es, the Attorney General’s Office has sent them a statement that this investigation seeks to refute if it took a criminally condemnable action after it abdicated in 2014, when it ran out of the protection privileges the king has before the law. The research will focus on the second phase of the construction of the "desert TAV", which links the cities of Medina and Mecca.

The investigation moves from the National High Court to the Supreme

So far, the Anti-corruption Prosecutor’s Office is investigating whether the Bourbon Prosecutor committed tax offences and money laundering, and whether the Bourbon Prosecutor was acquitted. However, State Attorney General Dolores Delgado has decided to raise the investigation to the Supreme Court. The former king of Spain is apprehended in the Supreme.

The journal Berria has gathered the trajectory of this case very well: "The investigation began at the National Hearing in late 2018, following a recorded conversation between former police chief José Manuel Villarejo, currently incarcerated, and Corinna Larsen, friend of Borbon, according to which the former Spanish head of state charged commissions for the construction of the TAV in Mecca in exchange for achieving a consortium of Spanish companies in 2011. The commissions, according to Larsen, amounted to EUR 80 million that were paid to the wife of an entrepreneur in Saudi Arabia, who gave half of the profits to an entrepreneur in Spain. This is Bourbon."
