Thanks for your considered reply and I think that we certainly have points of agreement. Your observation of agricultural EU migrant labour is most
pertinent and my understanding is that seasonal workers are now staying away from UK due weak Sterling, a perceived "hostile environment" and higher wages in other EU countries. Perhaps free movement of labour is not only a "red line" but also a "red herring" and we are in danger of shooting ourselves in the foot (that's enough metaphors!)?
The point I'm attempting to allude to is that this particular "red line" is a chimera that can be politically finessed by EFTA/EEA membership, whether Article 112 is invoked or not.
