Britain’s Queen Elizabeth II has canceled a planned trip to Wales because she is experiencing symptoms of gastroenteritis, a Buckingham Palace spokeswoman said Friday.

Elizabeth, who had been scheduled to visit Wales on Saturday, will now spend the weekend at Windsor Castle as usual, the spokeswoman added.

The queen’s health will be assessed in the coming days.

The queen had been scheduled to present leeks – a symbol of Wales’ patron saint, St. David – to members of a reserve battalion of The Royal Welsh infantry unit at a parade in Swansea on Saturday.

The event was to commemorate St. David’s Day, celebrated Friday.
