LONDON (AP) - Queen Elizabeth II has left a central London hospital after a one-day stay caused by a severe stomach bug.
She walked unassisted out of King Edward VII Hospital Monday afternoon wearing a red dress, and was driven away in a motorcade.
The hospital stay had initially been planned for two days. She has been suffering from gastroenteritis, a stomach and intestinal inflammation.
The 86-year-old queen has canceled her engagements for this week due to the illness. It was her first hospitalization in 10 years.
