it is illegal for a British merchant vessel to fly the Union Flag; British merchant vessels are encouraged to fly the Red Ensign; some vessel masters (not the vessel itself) are entitled to fly one of the variants of the Blue Ensign
It is improper for a foreign merchant vessel to fly the Union Flag; the correct courtesy flag is the Red ensign (although a commissioned warship may fly the White Ensign as a courtesy flag)
Only a commissioned Royal Navy warship may fly the Union Flag but only on the vessel's jackstaff; the correct ensign for such a vessel is the White Ensign
