UK's Queen Elizabeth Spent Night In Hospital, Says Buckingham Palace

The Queen attended hospital on Wednesday afternoon for some preliminary investigations and returned to Windsor Castle on Thursday, said the Buckingham Palace.

Queen Elizabeth II spent a night in hospital after being advised to rest and cancel a visit to Northern Ireland this week, Buckingham Palace said on Thursday.

"Following medical advice to rest for a few days, The Queen attended hospital on Wednesday afternoon for some preliminary investigations, returning to Windsor Castle at lunchtime today (Thursday), and remains in good spirits," a statement said.

Britain's domestic Press Association news agency said the trip to hospital was unannounced as it was expected to be a short stay, and also to protect the 95-year-old monarch's privacy.

But the overnight stay was for "practical reasons", it added, without disclosing the hospital concerned or the nature of the tests.
