Royal standard of the United Kingdom

The royal standard of the United Kingdom is the banner of arms of the monarch of the United Kingdom, currently Charles III. It consists of the monarch's coat of arms in flag form, and is made up of four quarters containing the arms of the former kingdoms of England, Ireland, and Scotland. There are two versions of the banner, one used in Scotland in which the Scottish quarters take precedence, and one used elsewhere in which the English quarters take precedence. Since the 1960s, personal flags for the monarch in their role as sovereign of other Commonwealth realms have been introduced.

The banner is flown to signify the presence of the monarch. It may be flown when they are present at one of their residences, from the car, ship, or aeroplane they are travelling in, and from any building they are visiting. The banner is never flown at half-mast, as a symbol of the continuity of the monarchy, since there is always a sovereign on the throne.

Although almost universally called a standard, in heraldic terminology the flag is a banner of arms, as it is a coat of arms in flag form; standards are more typically tapering flags on which heraldic badges and mottoes are displayed.

In England, Northern Ireland, Wales, the Crown dependencies and the British Overseas Territories, the flag is divided into four quadrants. The first and fourth quadrants represent the ancient Kingdom of England and contain three gold lions (or "leopards"), passant guardant on a red field; the second quadrant represents the ancient Kingdom of Scotland and contains a red lion rampant on a gold field; the third quadrant represents the ancient Kingdom of Ireland and contains a version of the gold harp from the coat of arms of Ireland on a blue field. The inclusion of the harp remains an issue for some in Ireland. In 1937 Éamon de Valera, then Taoiseach, asked Dominions Secretary Malcolm MacDonald if the harp quarter could be removed from the Royal Standard on the grounds that the Irish people had not given their consent to the Irish emblem being included. The request was denied, and the harp remains.

The modern Royal Standard of the United Kingdom, apart from minor changes (notably to the form of harp used to represent Ireland), dates to the reign of Queen Victoria. Earlier Royal Standards of the United Kingdom incorporated the Arms of Hanover and of the Kingdom of France, representing the title of Elector (later King) of Hanover and the theoretical claim to the throne of France, a claim dropped in 1800). The Hanoverian association terminated in 1837 with the accession of Queen Victoria who, being a female, could not accede to Hanover.

Famous Royal Standards of former British Monarchs include the Scotland Impaled Royal Standard of Queen Anne, the Hanover Quartered Royal Standards of King George I to George III, and the Hanover crowned Royal Standards of George III to William IV. The latter contained the Royal coat of arms of Hanover superimposed over what became the modern Royal Standard of the United Kingdom, although this particular standard's artistic representations of the banners of England, Ireland and Scotland in their respective quadrants was marginally different from the versions used today.

Since 1998 (the year in which Scottish devolution legislation was enacted) a separate version of the Royal Standard of the United Kingdom has been used by the monarch in Scotland, whereby the red Lion Rampant of the Kingdom of Scotland appears in the first and fourth quadrants, displacing the three gold lions passant guardant of England, which occur only in the second quadrant. The third quadrant, displaying the gold harp of Ireland, remains unaltered from that version used throughout the remainder of the United Kingdom and overseas. (Previously the same version of the standard was used throughout the United Kingdom).

The Scottish version of the Royal Standard was used to cover the coffin of Queen Elizabeth II during the journey from Balmoral to Edinburgh on 11 September 2022, during the procession on the Royal Mile from the Palace of Holyroodhouse to St. Giles' Cathedral on 12 September, and throughout the lying-at-rest period at St. Giles’, where the Royal Standard was surmounted by the Crown of Scotland, prior to being flown by the Royal Air Force to London on 13 September. During the flight from Edinburgh Airport to RAF Northolt, London, the Scottish version of the Royal Standard was replaced by the Royal Standard used in the rest of the United Kingdom.
