Queen Elizabeth II and Prince Philip have left Buckingham Palace in the wake of the coronavirus outbreak.
Following crisis talks, chaired by Boris Johnson, the 93-year-old monarch and her husband, 98, were rushed to Windsor Castle.
Should things worsen, there are plans to quarantine the couple at Sandringham, Norfolk.
Though the queen is reportedly in good health, a royal source says it was thought best she was moved as a precaution.
"The Palace hosts a constant stream of visitors including politicians and dignitaries from around the world," the source said.
