(2) In terms of how we trade with Europe we have an equal say in single market and customs union policy - by virtue of the European Council and the European Parliament. If anyone outside the EU wants to enter a trade deal with UK, we must have the same representation rights within those countries that we have with the EU.
So are you suggesting we would expect 1 to 1 representation in trading with US? Or 1 to 27 (as we have with EU)? or even 1 to 50 (If our representation is as a single state amongst many)?
