UK government buildings within the wider Whitehall area may fly the national flags alongside the union flag on their appropriate saint days. Flags should be flown at full mast all day. 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. The Union Flag only should be flown.
