Which kind of shows the EU for what it is doesn't it?
Power hungry. Controlling.
So if I make a deal with you and then you break your side of the bargain you think it would power hungry and controlling of me to stop holding up my side? Let's say we agree you can walk across my lawn on your way to work if I can use your bridge to get to the other side of the river on my way to work - according to you if you stop letting me cross the bridge, it would be power hungry and controlling of me to stop you walking across my lawn?
Switzerland signed a deal with the EU; if it stops honouring that deal, the EU is entirely within it's rights to stop giving them the access that the deal agreed.
