I don't know exactly, but it is the flag of St. George, so I doubt it has anything to do with when the Danes occupied parts of the UK, and the flag of St. George only applies to England, not the whole of the country. I do however know that the Scottish flag... the diagonal white cross on the blue background is the flag of St. Andrew, and that was because it was a cloud formation he saw before a battle. Anyway... back to the point, I wreckon that they all have crosses because they are all christian countries and all have saints associated, not because they share heritage.
