LONDON – Buckingham Palace officials say Queen Elizabeth II will resume her royal duties next week after a brief illness.

Officials said Friday the queen and her husband Prince Philip plan to attend a Westminster Abbey service Monday to mark Commonwealth Day with another event scheduled later in the week.

The 86-year-old monarch was hospitalized overnight on Sunday for treatment of gastroenteritis. It was her first hospitalization in a decade.

Officials said the queen’s overall health remains good and she is not cutting back on her activities, although taxing overseas travel has been reduced.

The 91-year-old Philip has been treated for heart disease in recent years. He has said he plans to attend fewer events and to scale back his charity events.
