Four months ago we could use the EU rules to freely export to any member country, or any country it had a trade agreement with. Now every EU country has to be treated as both part of the EU and a separate state. The rules are not new, despite claims in the press and on BBC they are old, the bivalve mollusc one is one we wanted put in place while we were members.
That for exporters and importers is dreadful, for financial services is a nightmare. The USA has multiple trade agreements and side deals with the EU, which we lost when we left. The USA prefers us to be inside EU because we formed a political bridge. The deals so far with countries simply replicate the ones we had through the EU, or are worse than that.
Exports to EU countries in January dropped by about 40%. Financial services are setting up abroad and many companies are simply leaving. The really odd one is we have less sovereignty now than before we left. UK has to follow EU rules or be penalized.
