@urbanlife - And how do you suggest animal checks are done? Agricultural products cross back and forth over the border. This is currently seamless. Milk from the north goes south to a dairy. Cream from that milk goes north to make baileys, for example.
it will start slow of course - Let me repeat those numbers: 177,000 lorries, 208,000 vans, and 1,850,000 cars cross the border. Around 30,000 people cross the border daily to travel to work. There are 268 different crossing points.
Given that Ireland is independent it can fund its own ambulances etc I assume, and extra funding will be made available to NI.
Which immediately contravenes the GFA which has stipulated the setting up of cross-border cooperative bodies.
The GFA also requires parity of rights north and south. Divergence from EU rights in the north will also contravene the GFA.
