Sophie, Duchess of Edinburgh Misses Oman State Banquet at Windsor Castle
Sophie, Duchess of Edinburgh was not at the state banquet for the Sultan of Oman at Windsor Castle on October 20, 2026.
The dinner is the King's formal white-tie dinner for a visiting head of state. It closed the first day of the sultan's three-day visit to Britain. It was the second state banquet the duchess missed in 2026, after the Nigerian state banquet in March, according to Town & Country.
She was there in the afternoon. The duchess joined her husband Prince Edward for a reception for the sultan, his family and his delegation in the Green Drawing Room at Windsor Castle earlier on October 20. That put the couple on the welcome party, but not on the evening seating plan.
The guest of honor was Sultan Haitham bin Tariq of Oman. His state visit, an official visit made at the King's invitation, was scheduled for October 20 to October 22, 2026, according to the Royal Family. The announcement came on September 3. The October 20 program included a formal ceremonial welcome, an inspection of the guard of honor, an exchange of formal greetings and private meetings with King Charles.
It was the first British state visit by a Sultan of Oman since 1982, according to the BBC. King Charles and Queen Camilla hosted it at Windsor Castle, the royal residence west of London, rather than Buckingham Palace, as reported by People. The Windsor hall used for state banquets seats about 160 guests, with room for up to 170.
The duchess came into the week after a busy stretch of engagements. In late September she visited The Hague for the International Civil Society Action Network's Women, Peace and Security Forum, where she met women peace-builders from more than 40 conflict-affected countries. The duchess serves as the royal family's representative for the United Nations' Women, Peace and Security agenda, which calls for women's inclusion in preventing conflict and rebuilding after it.
She also completed a six-day tour of Zambia focused on women's entrepreneurship, wildlife conservation and health care. Closer to home, she traveled to England's West Midlands for a memorial event for the Corps of Royal Electrical and Mechanical Engineers, the British Army branch that maintains military equipment.
What makes this stand out for regular royal-watchers is the split schedule. A daytime reception and an evening banquet can have different guest lists, especially with about 160 seats in the banquet hall. The duchess made the first on October 20. She did not make the second.
