That’s not how these things work in the EU.
Oh god, I’m arguing with chewie, kill me now.
It might not work like I have described Now but it Will because that is how bureaucratic or politburo works.
You simply cannot have an organisation structure/system etc that is inbetween because you will end up with an even larger mess. Naturally, you need to apply the bureaucratic system and in that sytem you will need to have an overall head. If not an overall head then you have a panel and in that panel you rule by iron fist of majority. That’s exactly where EU is heading … ouch!
If EU does not sign TTIP then EU needs to bow to Far East. Bow now!
Looks like you (join EU) are caught between the rock and a hard place.
