The Brexit brigade have already said they will be looking to join the single market...Part of the membership conditions state that there must be freedom of movement for workers...
Thats not going to happen..We will no doubt join the single market which will allow freedom of movement for workers in europe...No different than now..
They will want to come for....wait for it....MONEY
There will still be freedom of movement for workers if we want to be part of the single market....Not quite sure how that differs too much from us being part of the EU with the 4 yr benefit rule??
