Alderney, with the neighbouring islands of Herm, Sark, Guernsey and Jethou, constitutes the administrative bailiwick/district of Guernsey, an autonomous and by the British crown adminstrated territory
Alderney uses the flag of England, the red St. George's cross on white background, with the depction of the scutcheon of the island laid out in the centre. It is round with a golden border and shows a crowned, soaring, golden lion with red claws on green ground, holding a plant in his paw. In 2007, a Blue Ensign was also introduced. United Kingdom introduced a flag system in 1864 in which: • war ships fly the "White Ensign" (naval flag), a white flag often with an uninterrupted red St. George's-Cross and with the Union Jack in the upper staff quadrant of the flag, • merchant ships fly a "Red Ensign" (also named "Civil Ensign" → civil flag, the real merchant flag), a red flag with the Union Jack in the upper staff quadrant of the flag, and • governmental ships fly the "Blue Ensign" (flag for the use by the gouvernment → the actual state flag), a blue flag with the Union Jack in the upper staff quadrant of the flag. Since 1865, ships of regional or colonial governments, as well of offices and authorities, were allowed to use a Blue Ensign with a badge in the flying end.
