The Queen is in hospital "as a precaution" where she is being assessed for symptoms of gastroenteritis, Buckingham Palace has said.
A palace spokesperson said the 86-year-old monarch had been taken to King Edward VII Hospital in London by private car.
All official engagements for this week, including the Queen's trip to Rome, will be either cancelled or postponed.
