<P> The Royal Standards of the United Kingdom refers to either one of two similar flags used by Queen Elizabeth II in her capacity as Sovereign of the United Kingdom and its overseas territories . Two versions of the flag exist, one for general use in England, Northern Ireland, Wales and overseas; and the other for use in Scotland . </P> <P> Although almost universally called a standard, such flags when used in the United Kingdom are banners of arms, as they comprise the shield of the Royal Arms . Since the 1960s, Queen Elizabeth II has had several personal flags designed for her use as sovereign of certain Commonwealth realms . These heraldic flags are similar to those of the British "Royal Standard" in being banners of the nation's arms but feature a device found in the Queen's general personal flag (a blue disc containing a wreath of gold roses encircling a crowned letter' E') </P> <P> The Royal Standard of the United Kingdom is flown when the Queen is in residence in one of the royal palaces and on her car, ship or aeroplane . It may be flown on any building, official or private, during a visit by the Queen, if the owner or proprietor so requests . It famously replaces the Union Flag over the Palace of Westminster when the Queen visits during the State Opening of Parliament . The Royal Standard was flown aboard the royal yacht when it was in service and the Queen was on board . The only church that may fly a Royal Standard, even without the presence of the Sovereign, is Westminster Abbey, a Royal Peculiar . </P> <P> When the Queen visited the United States in 1992, she was provided with a Cadillac limousine that flew both her standard and the Stars and Stripes, an acknowledgement of the "special relationship" that exists between the two nations . </P>
