The Duke of Sussex was in the U.K. for an Invictus Games-focused trip
Prince Harry extended invitations to several royal family members ahead of the Invictus Games anniversary service in London.
PEOPLE understands that the Duke of Sussex invited his father, King Charles, his brother, Prince William and his sister-in-law, Kate Middleton, for the Service of Thanksgiving commemorating a decade of the Invictus Games at St. Paul’s Cathedral on May 8. Prince Harry’s Invictus-focused solo trip was a full-circle moment, as he hosted the first iteration of international adaptive sports tournament for wounded, injured and sick service personnel and veterans in London in 2014.
The Duke of Sussex, 39, was supported at the St. Paul’s service by several members from Princess Diana’s side of the family — his aunt Lady Jane Fellowes, his uncle Charles Spencer and his cousin Louis Spencer. Prince Harry was in good spirits as he arrived, happily greeting well-wishers outside of the historic church when the service concluded.
Princess Kate, 42, has been out of the public eye since Christmas, following her abdominal surgery in January, private recovery and the announcement of her cancer diagnosis on March 22. The Princess of Wales said in her self-written speech announcing her diagnosis that she looked forward to returning to work “when I am able,” though Kensington Palace outlined that any initial public events won’t necessarily signal a formal return to a regular schedule.
Prince William, 41, conducted investitures at Windsor Castle on the same day as Prince Harry’s Invictus Games service. The duty included awarding an MBE to Claire van Straubenzee for the Henry van Straubenzee Memorial Fund, an educational non-profit focused on Uganda named after Claire and Alex van Straubenzee’s son Henry, who died in a car crash in 2002 just before he was due to go to the African country to work in a school.
Henry’s brothers, Thomas and Charlie, are very close friends of Prince William and Prince Harry, who backed the charity as the only patronage they shared.
A few miles from St. Paul’s Cathedral, King Charles, 75, hosted the first garden party of the season at Buckingham Palace. The royal family has organized garden parties have been held since the 1860s as a way for the monarch to recognize community members for their public service. The festive event was attended by Queen Camilla, Princess Anne, Prince Edward, Sophie, the Duchess of Edinburgh, Prince Richard and Birgitte, the Duchess of Gloucester.
PEOPLE confirmed earlier this week that Prince Harry would not be able to meet with his father the King Charles during his U.K. stay due to the sovereign’s “full” schedule.
