All this fuss about chilled meats products and Northern Ireland.
Surely the solution is easy.
Any pack of chilled meat products from the UK destined for a supermarket shelf in Ulster has a ruddy great label slapped on the cellophane: "Not For Resale In The EU". Preferably with a Union Jack motif - end of.
No customs checks necessary for such products crossing the Irish Sea.
No customs checks necessary on the Irish Border.
Everybody happy.
If the Irish Food Ministry (Department of Agriculture, Food and the Marine, IIUIC) finds Seamus O'Malley flogging errantly-packaged Tesco's Cumberland Sausages in his corner shop in Waterford, then they can do Seamus over and fine him a few Euros.
You're going to tell me it ain't that simple, aren't you?
