In reply to doz generale:
I think the gist of the plan has been "we'll negotiate".
Until you know the outcome of those negotiations you don't know what situation you'll have to deal with and what to plan for. I don't see why this isn't pretty clear to most people who keep demanding a 'plan' all the time.
Ideally the UK wants to leave the EU and have control over the numbers of people who come into the country while maintaining its full membership of the single market. Now it's unlikely the EU will want to give us full access to the single market if we don't accept total freedom of movement.
So the 'plan' comes into play, we negotiate. This normally means a compromise on both sides until both parties come something they can live with. The exact nature of that arrangement is of course unknown yet. If we get total single market access then we'll probably have to compromise on immigration to some degree. If we're unwilling to compromise on that then we'll have to compromise on the amount of single market access we have. The EU don't want to give it away for free but they equally don't want to lose our trade given how weak the EU will be soon.
The point is, no one can known what the outcome will be so what plans you can make are pretty limited. What sorts of things do you think we can properly plan for in advance? and what suggestions do you have for such plans?
