My daughter has suggested that we, here, ask to renegotiate Protocol 3 with the Rep of Ireland as our EU link a sort of MannIN campaign. I dread to think how Gibraltar is taking it. Or the Channel Islands - perhaps they might wish to become a French territory! Or perhaps not :)
The Crown Dependancies of the Isle of Man and the Channel Islands have (or had...) their own relationship to the EU called Protocol 3.
This basically means we do not pay anything in to the EU, nor can we get any of the subsidies and grants etc, that the UK does. But we are allowed to trade with the EU without tariff barriers as long as we obey their regulations for goods and services.
So why would the UK leaving effect us? Because Protocol 3 says that in all negotiations/treaties etc. the Crown Dependencies will be represented by 'the UK as an EU member'.... So protocol 3 becomes void if the UK is no longer a member and we will face all sorts of barriers in anything where we come into contact with EU countries.
Maybe we should try something like in The City and The City. People who want to stay in the EU wear different coloured clothes, have different coloured buildings, etc. Build a big customs hall at St. Pancras. Go in one door from the EU, out the other and you're in Little England.
Federalisation along German lines might lead to a situation where London was institutionally able to cede. But this would take decades and doubt that any meaningful form of federalism or localism is likely to be on the cards.
This is just an unholy slow motion of a mess. I am depressed beyond words.
