The Princess of Wales, Kate Middleton, made a dazzling appearance at a state banquet hosted at Windsor Castle on March 18, 2026, coinciding with the visit of Nigeria’s president and first lady. This event marked a significant occasion, not just for the royal family but also for the strengthening of diplomatic ties between the United Kingdom and Nigeria.

For her first tiara outing of 2026, the Princess opted for the elegant Queen Mary’s Lover’s Knot Tiara, a striking headpiece that has become a staple in her royal appearances. This particular tiara is notable not only for its beauty but also for its historical significance, having been worn by the late Princess Diana. The Princess of Wales has showcased five different tiaras throughout her time in the royal spotlight, with this tiara already making two appearances in the previous year.
Princess Kate’s attire for the evening was designed by Andrew Gn and featured a vibrant green shade, likely a deliberate homage to the colours of the Nigerian flag. Complementing her ensemble were exquisite earrings belonging to the late Queen Elizabeth II, and she also donned the Royal Family Order of King Charles, as well as the Royal Victorian Order sash and star, which added a further touch of royal dignity to her look.
The Nigerian state banquet was a key moment in the state visit agenda, which was designed to strengthen bilateral relations. King Charles and Queen Camilla welcomed Nigerian President Bola Tinubu and his wife, Oluremi Tinubu, as part of these official events. Such state visits are meticulously coordinated through both the Foreign and Commonwealth Office and the Royal Household, and they often feature lavish banquets on the first evening of the guest country’s visit.
Notably, Windsor Castle has become the venue of choice for many recent state visits, as Buckingham Palace is currently undergoing renovations. The elegant St. George’s Hall, where the banquet was held, has previously hosted numerous memorable royal occasions, including the reception for Prince Harry and Meghan Markle’s wedding.
The banquet catered to an impressive guest list of 160 individuals, with palace staff dedicating several days to create a visually stunning atmosphere. The lavish table was adorned with exquisite floral arrangements sourced from the gardens at both Windsor and Buckingham Palace, adding a touch of splendour befitting the royal occasion.
As the Prince and Princess of Wales take on greater roles within royal duties following King Charles’s accession to the throne, their participation in such high-profile state visits has become increasingly prominent. They played vital roles in several state engagements throughout 2025, welcoming international leaders from France, Germany, and the United States—demonstrating their commitment to fostering diplomatic relations.
With the festivities of the evening reflecting the significance of these international relationships, the banquet served as an opportunity to build rapport and strengthen ties between the United Kingdom and Nigeria. The charming and elegant atmosphere, coupled with the depth of royal tradition, underlined the importance of cultural and diplomatic exchange in today’s global landscape.
As the celebrations unfolded at Windsor Castle, the Princess of Wales shone not only as a member of the royal family but also as an ambassador for British values and culture, further establishing her role within the monarchy as it continues to evolve.
