LONDON (AP) - British media say Queen Elizabeth II left the hospital on Monday afternoon after a one-day stay caused by a stomach ailment.

It had been announced earlier that she would stay for two days because of gastroenteritis.

The 86-year-old queen fell ill last Friday and was being treated at Windsor Castle until Sunday, when she was moved to a central London hospital as a precaution.

It is the first time she has been hospitalised in a decade. Palace officials say she is otherwise in good health.
