  1. Where a building has two or more flag poles the appropriate national flag may be flown in addition to the union flag but not in a superior position. UK government buildings within the wider Whitehall area may fly the national flags alongside the union flag on their appropriate saint days.
  2. Flags should be flown at full mast all day.
  3. Flags should be flown on this day even if Her Majesty does not perform the ceremony in person. Flags should only be flown in the Greater London area.
  4. Where the European flag is flown on this day, the Union Flag should fly alongside the European flag and, on UK government buildings that only have one flagpole, the Union Flag should take precedence.
  5. The Union Flag only should be flown.
