I kinda feel sorry for the around 1 million UK citizens that live in spain. this exit won't be pretty.

 

Just beacuse the Uk leaves the EU doesn't mean it's falling apart... hell it won't surprise me if Scottland and Ireland leaves the UK and rejoin the EU.

Never said it was. I just want to know if (hypothetically) it would happen and what the consequences could be.

I'm asking this because I see people want to leave the EU just for the sake of leaving it, just like I get the feeling from the UK. Reachin the point of leaving it, and then not having a clue of what doing afterwards and not being prepared for the consequences.
