Found the graphs and the linked article interesting:
Basically, it suggests the EU, especially Germany, needs the UK more than we need the entire EU.
When the UK is not counted as part of the EU we become the 2nd-biggest buyer of EU goods in the World, almost as large as the USA and far more important to the EU27 than China.
Quite simply, the UK does dreadfully out of the Customs Union
Tariff-free access merely allows EU conglomerates to flood the UK market, to the detriment of UK manufacturing and jobs. It only benefits multinational companies, not the 92% of British business who do not trade with the EU.
It forces the Common External Tariff on the UK, which means UK consumers pay far more for imported goods than they need to. It works in the interests of EU27 countries, not in the UK’s interests.
