In England, evidence that England continues to consider itself the ruler of, rather than a member of a union with, Scotland and the North of Ireland, never mind Wales (which is not represented at all). In Scotland, evidence of a persistent insult (the English St. George Cross is superimposed on the Scottish St. Andrews Cross). In the Republic of Ireland, an astonishing testimony to English arrogance, given the insistence of the English on not changing the flag after 1922 to reflect the fact that Ireland threw the English out.
