The Duchess of Kent, who died at 92, became the first British senior royal to convert to Catholicism in centuries in 1994. Her funeral at Westminster Cathedral on September 16 will be the first Catholic royal funeral in modern British history, marking a significant shift as King Charles III attends, breaking a 400-year-old tradition. An online book of condolence is open on the royal website.
