LONDON - Britain’s Queen Elizabeth II has cancelled a planned visit to Wales on Saturday due to a bout of gastroenteritis, a Buckingham Palace spokesman said. The 86-year-old monarch had been due to attend a military celebration in the city of Swansea to mark St. David’s Day, the national day of Wales. “The queen will no longer go to Swansea tomorrow,” a spokesman told AFP. “She is experiencing symptoms of gastroenteritis. The queen is currently spending the weekend in Windsor as usual.” Gastroenteritis is an infection of the stomach and bowel, with common symptoms including vomiting, diarrhoea and dehydration. The spokesman said that no decision had yet been made on the queen’s trip to Rome scheduled for next Wednesday and Thursday, when she is due to meet Italy’s President Giorgio Napolitano alongside her husband Prince Philip. “She is currently being assessed and she will be assessed in the coming days,” the spokesman added. The queen had been due to present St. David’s Day leeks - a national emblem of Wales - to members of 3rd Battalion The Royal Welsh, of which she is colonel-in-chief. Swansea Council said the ceremony would go ahead as planned with the Lord Lieutenant of West Glamorgan, Byron Lewis in attendance.
