Recently I have seen a couple of articles about a rise in support for Welsh independence. A few years ago I would have thought it fanciful, but there are many less populated independent countries, including within Europe.
For them to at least keep their current economic status, they would need to make some very quick trade deals with Westminster and the EU, and perhaps eventually join the EU if the Welsh public wanted it by whichever time.
With my admittedly limited knowledge, I would estimate that the industrial areas in the south would potentially be fine, but some areas further north and west would be very reliant on farming and/or tourism. Am I talking rubbish or would it be viable?
