As you may know or not know the citizens of the UK will vote on the 23rd of june on the continuation of the membership of the EU. This choice of course is entirely their's to make but once they have made it all EU members will have to deal with the outcome.

I was wondering what the reaction of the EU should be according to people here if the UK votes to leave the EU. After having asked this I would ask members who are going to vote in the upcoming referendum to refrain from reacting here, as this is not their discussion.

So what do you think?

Should the EU cooperate with the UK to give it full access to the common market without the UK having to apply the rules concerning the 4 freedoms, more particular the one about the freedom of movement of workers/persons?

Should the EU cooperate with the UK in a way to make a deal possible that puts the UK on a par with countries like Switzerland and/or Norway? This would mean the UK would not get the freedom to revoke any legislation that is required for the function of the common market and in the future would be obliged to apply new legislation from Brussels.

Should the EU retaliate against the UK by treating the UK as a 'third country', which has no blanket access to the common market?

Should the EU react in any different way? If yes please explain.

My emotional reaction would be to choose option 3, but I still choose option 2 as I do not want to see a situation in Europe which could deteriorate rapidly into the old chaos on the continent.
