Due to a 'personal matter,' Prince William has pulled out of the royal event

Due to a 'personal matter,' Prince William has pulled out of the royal event.

Prince of Wales will be absent from the ceremony honouring Constantine, the former monarch of Greece, at Windsor Castle.

The Prince of Wales has decided not to attend a memorial ceremony at Windsor Castle for one of his godfathers owing to a "personal matter." 

Kensington Palace declined to provide details but said that the Princess of Wales, recuperating from stomach surgery, is progressing well. 

William was scheduled to give a reading at the ceremony at St George's Chapel for Constantine II of Greece, who passed away in January of the previous year. 

The Prince of Wales contacted the former Greek king's family, who were present at the ceremony, to inform them that he would not be able to attend. 

Kate is now on a break from formal royal duties after surgery in January and will resume after Easter.

King Charles will be absent from the service due to ongoing treatment for an unidentified cancer.

Charles, residing at Windsor Castle, is scheduled to depart the Berkshire estate on Tuesday morning. 

Many foreign royals journeyed to Windsor for the service, but the monarch did not anticipate having private meetings with them.

Pavlos, Constantine's oldest son, will read in place of William.

The Duke of York accompanied his family members, including his ex-wife Sarah, the Duchess of York, Princess Beatrice, the Princess Royal, Zara, and Mike Tindall. They arrived at the chapel after being transported to the castle courtyard by carriage. 

The last member of the British royal family to arrive was the queen, who was driven from the castle to the 15th-century chapel. The Right Rev Christopher Cocksworth, the dean of Windsor, welcomed her at the Galilee Porch.

The monarch was said to have a strong relationship with Constantine, his second cousin and first cousin once removed, and a sailing companion of the late Duke of Edinburgh. Constantine passed away aged 82 in January of the previous year, several years after being removed from power in a military coup.
