The European royal family commemorates King Constantine: Queen Letizia of Spain, her disgraced father-in-law King Juan Carlos and the Danish princess gather around the Greek royal family at a commemoration in Windsor

Europe’s royal households gathered today to attend King Constantine’s commemoration in Windsor.

Greece’s last king died on January 10 last year at the age of 82 after months of illness – more than 50 years after he was exiled in a military coup.

The service at St George’s Chapel was attended by members of the Greek, British, Spanish and Danish royal families.

The Prince of Wales, 41, was expected to give a lecture at the service of his late godfather but pulled out at the last minute due to personal reasons, leaving Queen Camilla to represent the British royal family.

King Constantine’s eldest son, Crown Prince Pavlos, led the Greek royal family in the thanksgiving service together with his wife Chantal-Marie.

The head of the Greek royal family, 56, opted for a navy blue double-breasted suit for the occasion, while his wife looked elegant in a burgundy dress and matching cape.

Meanwhile, Crown Princess Olympia, 27, cut a glamorous figure in a figure-hugging navy blue square-neck dress and black oversized coat as she walked alongside her brothers Achileas-Andreas, Constantine Alexios and Odysseas-Kimon.

The model completed her elegant look with sheer navy blue tights and a miniature black patent leather handbag.

Queen Letizia, 51, looked solemn in a navy blue knee-length dress, which she teamed with matching heels and a scarf.

The mother-of-two arrived arm in arm with her husband King Felipe, whose mother Queen Sofia, 85, was King Constantine’s older sister.

In addition, disgraced former Spanish king Juan Carlos – who now lives in the United Arab Emirates after abdicating in 2014 – was also in attendance.

King Constantine’s younger sister, Princess Irene of Denmark, 81, also attended today’s commemoration and was pictured next to her sister Sofia.

Today’s service in St. George’s Chapel is held in honor of King Charles’ close friend and great-nephew, Constantine II, the former ruler of Greece.

The late king – the only son of King Paul and Queen Frederica – was also the Duke of Edinburgh’s cousin and Prince William’s godfather.

Prince Andrew was spotted with his ex-wife Sarah Ferguson at the Thanksgiving service.

It is understood the Duke of York is attending as a member of the British Royal Family and was invited by the Greek Royal Family.

King Constantine’s funeral was attended by Princess Anne and her husband, Vice Admiral Sir Timothy Laurence, in January 2023.

Constantine became king of Greece in 1964, but was ousted from the throne when the monarchy was abolished in 1973.

King Charles is not expected to attend his memorial service in Windsor after retiring from public life following his cancer diagnosis.

Camilla’s role in the agency will see her take charge again as she tries to take the pressure off her husband.

Members of the royal family have rallied behind the king, with Prince William returning to his duties after spending time caring for his wife, Princess Kate.

Due to a separate health crisis, the Princess of Wales was admitted to the London Clinic for a planned abdominal operation, and will be unable to fulfill royal duties until at least Easter.

Last month, Greece’s royal family put on a somber display as they attended a memorial service to mark one year since the death of King Constantine.

He died “of a stroke”, local media reported, after several hospital admissions in the previous months.

High-profile royals including Constantine’s son Crown Prince Pavlos and Dowager Queen Anne Marie attended a private ceremony at the former summer palace of Tatoi, just outside Athens.

Last year, Crown Princess Olympia split from her boyfriend of three years Peregrine Pearson – shortly before the aristocrat was pictured kissing Game of Thrones actress Sophie Turner.
