One of the most fundamental agreements is the demand of EU, that if Switzerland stock market is to have access to the EU - they must treat all EU citizens as having equal rights to swiss citizens on Swiss soil.
The EU really does not respect sovereignty. It is annexation by other means.
The swiss rightly say Nein!
Net result the market will be turned off.
It is petty and vindictive.
That ideology prevents sensible deals being done.
Which is our problem over Northern Ireland.
All ideologues create the seeds of their own destruction because of refusal to compromise. And so it is with EU.
