The Prince of Wales invited Princess Beatrice, Princess Eugenie, Zara Tindall, and more royals to accompany him today.

At Buckingham Palace today, Prince William hosted a Garden Party on behalf of his father, King Charles.

It is the fourth Garden Party of 2024 so far; King Charles hosted the first one of the season, joined by other senior working royals including Queen Camilla, Prince Edward, Sophie, the Duchess of Edinburgh, and Princess Anne. At today’s fête, Prince William was joined by the Duke and Duchess of Gloucester, and he invited younger non-working members of the royal family as well: his first cousins, Princess Beatrice, Princess Eugenie, Zara Tindall, and Peter Phillips. His younger cousins Lady Louise Windsor and James, Earl of Wessex, both of whom are in school, were not in attendance.

The Garden Parties are an annual royal family tradition. Per the official royal family’s website, “Over the course of each year, over 30,000 guests are invited to spend a relaxed summer afternoon in the beautiful gardens of Buckingham Palace or the Palace of Holyroodhouse.” They add, “Garden Parties are an important way for members of the Royal Family to speak to a broad range of people from all walks of life, all of whom have made a positive impact in their community.”

According to Kensington Palace, at today’s event, Prince William will meet guests from his and Kate Middleton’s patronages, military affiliations, and passion projects. The Princess of Wales will not be in attendance as she continues to receive treatment for cancer; yesterday, a senior aide revealed that she will “return to work when she has had the green light from doctors,” which has not happened yet.
