LONDON (AP) — Buckingham Palace says Queen Elizabeth II is feeling poorly and has cancelled a planned appearance.

The palace said in a Thursday statement that the 92-year-old monarch "is feeling under the weather" and will not attend a morning service at St. Paul's Cathedral. The service marks the 200th anniversary of the Order of St. Michael and St. George.

The queen has had a busy schedule in recent weeks, including appearances at the Royal Ascot horse show.
