King Felipe VI of Spain sent King Charles III of the United Kingdom a letter of condolence today after the passing of Queen Elizabeth II.
The Spanish Royal Household also posted pictures of when King Felipe and Queen Letizia visited Queen Elizabeth for a state visit in 2017.

King Felipe also ordered his royal standard to fly at half staff wherever he may be.
Spain’s Royal Family and the Spanish government are likely to send a robust delegation to Queen Elizabeth’s funeral and King Charles’ coronation.
