You can't just hold a referendum to decide the relations between Switzerland and the EU -- the EU also gets to have a say. We have been incredibly patient with Switzerland in this regard but it can't continue. You must respect the agreements we already have with you and you cannot dictate the terms of new agreements with us.

(Background: some of the agreements with Switzerland have run out and we need new ones to replace them. Both sides continue as if the old agreements are still valid, Switzerland because it would hurt the country enormously if we didn't, the EU because it avoids antagonizing Switzerland and because it would slightly annoying if we didn't. We can literally take our marbles and go home without breaking any treaties with Switzerland. Many Swiss don't seem to understand that.)
