Princess Anne is set to miss one royal tradition on her birthday next week. Certain royal birthdays and anniversaries are marked by the ringing of the bells at Westminster Abbey, including for the Queen, the Duke of Edinburgh, their children, the Duke and Duchess of Cambridge and their children.
However, following the latest guidelines from the Church of England and the Central Council of Church Bell Ringers, ringing at the Abbey by their volunteer bell ringers is currently suspended during the coronavirus outbreak, as noted on the church's website.
