making it possible/attractive to destroy onshore production.
Sadly the real culprit here is the British people who have long regarded foreign as "better" whether it be cars or electronics or even food and beer and cider. French people still loyally buy French cars despite their poor quality and Italians still buy FIATs. We buy foreign.
Sadly its all over now and no going back. The Vauxhall plants will close as soon as the French factories are short of work, just like happened with the Rootes Group. The Mini factory is not to get the investment to keep it operating fully as EVs come along - again it will eventually shut. Even Honda, in shutting its UK plant, switched production back to Japan.
