Britain's Queen Elizabeth decided on Wednesday to rest for the next few days on advice from doctors and cancelled a planned visit to Northern Ireland, Buckingham Palace said, Reuters reports.
The palace did not say why the queen had been told to rest, though it said the 95-year-old monarch was in "good spirits" and looking forward to visiting Northern Ireland in the future.
