“For now, I prefer for personal reasons which concern nobody but myself, to continue residing in a permanent and stable manner in Abu Dhabi,” Juan Carlos wrote to his son, Spain’s reigning monarch Felipe VI, in a letter published by the royal family.

However, the former Spanish king did add that he intends to visit Spain on a regular basis to see family. 

“It seems timely to me to consider my return to Spain, but not immediately,” Juan Carlos wrote, five days after Spain’s public prosecutor published its decision to drop all three investigations against him.

Juan Carlos went into self-imposed exile in the United Arab Emirates in 2020 amid the probes, which included allegations of possible illegal commissions linked to a high-speed rail project in Saudi Arabia that was awarded to a Spanish consortium in 2011.

While he was never charged with any crime, the probes tainted his reputation and that of the Spanish monarchy.

Felipe has taken steps to distance himself from his father, who abdicated from the Spanish throne in 2014.

In Abu Dhabi, Juan Carlos said he “found peace, in particular for this period of my life even though, naturally, I will frequently come back to Spain”.

Juan Carlos was previously celebrated as a key figure in Spain’s transition to democracy following the death of dictator Francisco Franco in 1975.
