No they don’t. If they did, then the EU would be more Britain-like. There is only one country that controls the EU.
Nah...the Brits are able to prevent the EU from getting too integrated and to enable them to keep their free internal market with the EU
Britains position right now is fine -- not too close, not too far. it shouldn't muck in with France and Germany, but it shouldn't cut itself out either.
