Crown Princess Olympia of Greece cuts a sombre figure as she is joined by her parents and siblings at her grandfather King Constantine’s memorial service in Windsor

The Greek Royal Family put on a united front today as they arrived at the memorial service for the King Constantine in Windsor. 

Crown Princess Olympia, 27, cut a glamorous figure in a slim-fitting navy square-necked dress and black oversized coat as she arrived at St George’s Chapel with her brothers. 

Her father Crown Prince Pavlos , 56, opted for a navy double-breasted suit and matching tie for the occasion.  

Crown Princess Marie-Chantal, 55, looked suitably chic in a burgundy dress and matching wrap.

The mother-of-four completed her ensemble with some matching suede heels and a black leather clutch bag.

Meanwhile, Pavlos’ brother Philoppos and his wife Nina arrived arm-in-arm and dressed in navy.

Princess Nina opted for a textured navy co-ord with a peplum skirt and matching headband. 

Today’s service will be attended by several of the ruling houses of Europe, including the former King of Spain.

The Prince of Wales, 41, was expected to give a reading at his late godfather’s service but pulled out at the last minute due to personal reasons.  

William called the Greek royal family to apologise, while Kensington Palace confirmed the Princess of Wales was ‘doing well’ as she continues her abdominal surgery recovery at home. 

Today’s service at St George’s Chapel is being held in honour of King Charles’ close friend and second cousin Constantine II, the former ruler of Greece. 

The last King of Greece 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 late King – who was the only son of King Paul and Queen Frederica – was also the Duke of Edinburgh’s nephew and Prince William’s godfather.

Prince Andrew was spotted arriving for the thanksgiving service along with his ex-wife Sarah Ferguson.

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 in Windsor after drawing back from public life following his cancer diagnosis.

Camilla’s role in the service will see her again taking the reigns as she works to take the pressure off her husband.

Members of the Royal family have rallied around the King, with Prince William returning to duties after spending time caring for his wife Princess Kate.

In a separate health scare, the Princess of Wales had been admitted to The London Clinic for planned abdominal surgery, and she will not be able to perform any royal engagements until at least Easter.

Last month the Greek royal family put on a sombre 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, following several hospital admissions in the months before.

High-profile royals, including Constantine’s son Crown Prince Pavlos and widow 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.
