"Remain spin..."
Sigh... the UK is going to suffer economically in the event of a No Deal exit. That is almost certain. The only question becomes to what extent this occurs. Now, Leave supporters can, with perhaps some reasonable justification, claim that such suffering will be "worth it", in order to get what they want or what they voted for -- although note that there are divisions even within the Leave camp over whether "No Deal" is an objective worth pursuing or not. What they have no grounds to do is to insist that No Deal secures everything at once: sovereignty, economic security or even economic benefits, and superb new trading arrangements. To claim that No Deal is just winning on all counts is ridiculous and flies in the face of all the available evidence.
Here, we have investment lost from the country in part because of the uncertainty that in particular a No Deal Brexit implies. Granted, there are other factors in this decision -- the impact of Diesel regulations has played a part too -- but there it lies, as plain as day, in the announcement released by Nissan. There is no spin here.
It is notable, too, that at the time near the end of 2016 when Nissan's decision went the other way, Brexit supporters across the site were cheering and celebrating, and insisting that their decision then showed up "Project Fear" as a sham. Now they have cancelled that decision. It stands to reason that, at the very least, this complete reversal from 2016 should give decent grounds for re-evaluating that assessment.
