From Iain Johnstone, Brook:
I have just looked a website (referred to by the BBC webpage) which is supposed to give accurate details about British counties.
For the inquiring mind, have a look at county-wise.org.uk/counties/county-confusion/, a website for the Association of British Counties.
There is a county list down the right-hand side, which jumps from Inverness to Kent — nowhere on this list is any mention of the IW.
Digging further, by looking at Hampshire, the mystery is solved: "Across the Solent is the Isle of Wight, a self-reliant island (and once a separate Jutish kingdom) but a part of Hampshire nevertheless".
It’s amazing what you can learn from the internet as I really did not know this as, probably, many others don’t.
Nowhere on this site is a contact to correct this error so it has to remain (unless the CP waves its big stick at them).
County confusion is about right — pity they are suffering from it themselves,
