The Constitution also establishes in article 60 that the guardian of the King or Queen during their minority cannot be the same as the person who acts as regent, unless the regent is the father, the mother, or a direct ancestor of the King. A parent can be guardian while he or she remain widowed. If the parent marries again, the parent loses the guardianship, and the Cortes Generales shall appoint a guardian who must comply with the same requirements as to be regent.
