Oh yes, Gerry, there is agreement about the geographic boundaries -
it is just that people outside the UK find it confusing unless they
learn a little geography.
To say there is agreement about boundaries is a slight exaggeration. The English army occupied the town of Berwick-upon-Tweed (which then was one of Scotland's major cities and its most important port) in 1292, and it has never been returned to Scottish administration. Its local football team, however, plays in the *Scottish* League. Indeed, Berwick-upon-Tweed may be considered to be still at war with Russia, because it is separately listed as a Crown dominion on official documents at the commencement of an 18th century war between the United Kingdom and Russia, but it does not appear on the peace treaty at the end of the war.
Also, for many years, official British government documents refused to recognise the county of Monmouth (now better known under its Welsh name of Gwent) as being part of Wales, and within living memory still referred to Wales as 'Wales and Monmouth'.
