To be fair, I think the whole world economy is in a state of 'unpredictability' . . and I'd like to think we (the UK) would rid ourselves of any shackles that *may* end up dragging us into a scenario where we rely on the rise or fall of others.
If the EU is going through . . or heading towards . . some kind of failure in its economic certainty, I'd hope we could escape some of the fallout by distancing ourselves from it.
probably not explained very well, but you should get the gist . . .
