Correction, flag of the United Kingdom. The flag of Great Britain doesn't have the St Patrick cross as Ireland was not fully incorporated under the crown until 1807 I.e the formation of the United Kingdom of Great Britain and Ireland. Wales is not featured because it's a principality, not a kingdom.
The Border Between the 'Two Englands'. In Great Britain as in the US, two cultural sub-nations identify themselves (and the other) as North and South. There is a place used as shorthand for describing the divide, with the rougher, poorer North and wealthier, middle-to-upper-class South referring to each other as ‘on the other side of the Watford Gap’.
