King Charles and Queen Camilla are set to undertake a State Visit to Spain in 2027, it has been reported.
This would mark the first official British royal State Visit to Spain in nearly four decades, should the monarch, 77, and his wife, 79, travel to the country.
The last such occasion took place in 1988, when Queen Elizabeth II and the late Duke of Edinburgh were hosted by then-King Juan Carlos and Queen Sofia.
Precise dates for the forthcoming trip have yet to be officially confirmed, according to reports in Hello!.
During the visit, Their Majesties are expected to be received by their Spanish counterparts, King Felipe and Queen Letizia, as is customary on outward state visits of this nature.
Whether the couple's daughters, Princess Leonor, 20, and Infanta Sofia, 19, will participate in proceedings remains uncertain.
However, should a State Banquet form part of the programme, as is typical on such occasions, the two young princesses could have the opportunity to wear tiaras for the first time at an official engagement.
GB News has contacted Buckingham Palace and Casa de Su Majestad el Rey (the Royal House of Spain) for comment.
Such Banquets ordinarily attract around 150 guests and feature formal speeches and toasts exchanged between the respective heads of state.
State Visits serve a crucial function in bolstering the United Kingdom's diplomatic relationships abroad.
When foreign heads of state are welcomed to Britain, the monarch and other members of the Royal Family greet them with a ceremonial reception at Horse Guards Parade.
The Royal Collection has previously curated themed displays to mark such occasions; during King Felipe's 2017 visit, for instance, an exhibition featured items connected to Queen Ena of Spain, a granddaughter of Queen Victoria and Felipe's own great-grandmother.
Outward state visits, where the King and Queen travel overseas, tend to follow a comparable format, frequently incorporating a formal banquet.
The British and Spanish Royal Families have built a warm rapport in recent years.
Felipe and Letizia attended King Charles's Coronation at Westminster Abbey in 2023, where they were spotted in conversation with the newly crowned King at a Buckingham Palace reception for overseas guests.
The Spanish royals also paid their respects at the funeral of Queen Elizabeth II, viewing her coffin during the Lying-in-State at Westminster Hall.
Felipe previously visited Charles for an audience at Clarence House in November 2022, with the pair sharing a jovial exchange.
The Spanish King and Queen last made a full State Visit to Britain in July 2017, during which Felipe addressed both Houses of Parliament.
