So there's a couple of things to note about this situation:
1) Scottish referendum. There really is no basis for another one. It is desperate opportunism on the part of the SNP. London has a larger population and voted more overwhelmingly to stay in. Whilst rumours have circulated about a city state London in reality that could never happen. Scotland leaving would mean a land border with England, something inconceivable as things currently stand. Scotland would also need to take on the Euro which completely changes their financial models. Furthermore, the impact this result will have on the EU has to be accounted for. Is it going to be a more attractive proposition than staying?
2) There were 2 distinct groups who voted leave. The working class who have felt marginalised and ignored by politicians and globalisation. This was a significant win for them long term. The freedom of movement has evolved in a way that is detrimental to the working man. Secondly there were those who wanted to regain the democracy. These people essentially want more tax control and freedom from things like CAP. Often ignored in the debate was that both of these groups had very legitimate claims. Instead of listening to the root causes people just called them racists and bigots which was unhelpful.
3) Long term the economic picture will recover. I don't doubt that at all. What will be defining about this is how the EU react. If they take the hard-line stance to deter future withdrawals things will get messy quickly. Britain will be left very damaged but the EU will end up the same. There is little room for error from them at the moment with the banking crisis in Italy looming, anti EU feeling across Europe and Greece still a major issue. The other path for them is to reform. Something has to give for the disconnect between politicians and people to disappear.
Already there are 2 sides forming in Europe. Merkel and the eastern countries want to take this slow and rework our relationship, France wants to cut the cord and punish us.
I think people will end up surprised at how effective this exit will be. Behind all the posturing on both sides is a serious need for agreement.
I voted to remain but I was on the fence for quite a while. The vote is done now, there will be a change in the relationship with Europe. What will be interesting is how the leave leaders woo those who voted remain to support their new plan. I for one do not see us isolating ourselves, rather continuing our economic relationship with Europe whilst disentangling ourselves from the political beast theat is the EU.
