The Spanish monarch is retiring from public life five years after abdicating to allow his son to take over the reigns. The 81-year-old had been King between 1975 until 2014. But as opposed to continuing on, he confirmed he would abdicate his role.
According to PEOPLE, he has now shared his retirement plans with son King Felipe VI.
In the letter, he says he had considered retiring last year when he was 80.
But he wanted to be around to mark the 40th anniversary of the Spanish Constitution in Congress in December.
In his letter, the former King said: “It was a solemn act, full of emotion for me, that evoked, with pride and admiration, the memory of the many people who made the political transition [to democracy] possible and renewed my feeling of permanent gratitude toward the Spanish people, the true architect and leading protagonist of that transcendental stage of our recent history.”

Previously, the monarch had spoken to the chief of the royal household Rafael Spottorono about his plans to abdicate.
El Mundo reported him as saying : “I do not want my son to wither waiting like Prince Charles.”
King Carlos’ retirement officially begins on June 2.
That is five years exactly after his abdication.
Prince Charles has become a figure of fun over his long wait to become King.
His mother, Queen Elizabeth II has been on the throne since 1952.
The 93-year-old formally asked the Commonwealth Heads of Government to appoint him as her successor of the association of Britain and its former colonies.
At the time, the move was rare.
In a statement she said: ““It is my sincere wish that the Commonwealth will continue to offer stability and continuity for future generations and will decide that one day the Prince of Wales should carry on the important work started by my father in 1949.”
