A day after the tragic death of their son-in-law Thomas Kingston, Prince and Princess Michael of Kent attended a memorial service.

Kingston, married to their daughter Lady Gabriella Windsor,

was found deceased at a home in Gloucestershire on Sunday evening.

His death, though unexpected, is not being treated as suspicious, and an inquest will be conducted.

Despite the grief, the royal couple joined a Thanksgiving service at Windsor Castle, honoring Greece’s late King Constantine.

The service was attended by members of the Greek Royal Family, including Sheikh Anne-Marie and Crown Prince Pavlos.

King Charles and Queen Camilla expressed their condolences, stating, “The King and Queen join

Prince and Princess Michael of Kent in their grief over the loss of a much-loved family member.” They sent

heartfelt thoughts to Lady Gabriella and the Kingston family.
