Devon and Cornwall will be inundated with refugees? Ifs, maybes, and conjecture

[Devonian]

Yes and you still haven't given any examples of an event that "could" cause max evacuation (circa 20M) of London and the South East.

You simply seem hell bent on promoting doom and gloom for the SW and are trying to make up scenarios to fit your arguments, you only have to look at the footer in your messages to see your attitude coming through:

"Yes move to the South West it is only 90 minutes from London and Brum that's why 9 million Londoners and 5 million Brummies have the same idea. There is nothing of interest for you in the north or Scotland"
