Buckingham Palace has announced that the funeral for Katharine, Duchess of Kent, will be held at Westminster Cathedral on 16 September, with a Requiem Mass in the Catholic tradition and the King and Queen among the senior royals expected to attend.

The duchess, who died on Thursday at the age of 92 at Kensington Palace, will be given a private family service at the cathedral before her coffin is taken to the Royal Burial Ground at Frogmore in Windsor. Buckingham Palace said the Requiem will mark the reception of the coffin into Westminster Cathedral and will be attended by close family.

The palace confirmed that the duchess’s coffin will remain in the chapel at Kensington Palace until the evening before the funeral, when it will be conveyed to Westminster Cathedral. The duchess was a practising Catholic, and the service will be a Requiem Mass — a Roman Catholic funeral rite. Buckingham Palace described the service as private, with the family to carry out subsequent burial arrangements at Frogmore.

Officials noted that the planned service is the first Catholic funeral for a member of the Royal Family in modern history. The duchess had long been associated with Catholic practice, and the choice of Westminster Cathedral reflects that faith. The palace’s statement made clear the arrangements would follow Catholic liturgy for the funeral.
