Re: A false argument
"If we do leave (in my view, we should stay), what is to prevent those workers from still working in the UK? Nothing from the EU side of things."
It's pretty clear that for most people wanting to leave, immigration is the key factor.
If the exit campaign's stance is that we'll still allow free movement of people after an exit it rather suggests that they are conning people.
If exit means "still have to pay, no longer have a say", the Norway model if you like, it looks pretty daft.
