“While we have taken this decision for business reasons, the continued uncertainty around the UK’s future relationship with the EU is not helping companies like ours to plan for the future.”

There it is, in black and white, from Nissan chairman Gianluca de Ficchy, explaining part of the reason why the firm has decided not to make the next-generation X-Trail in the UK after all.

And still some argue they know better than the people who made the decision, and claim that Brexit is nothing to do with it.

What’s more, this isn’t an argument based around Leave or Remain. The swipe, if I can describe it as such, by de Ficchy isn’t on the impact of Brexit itself (he doesn’t have a crystal ball, after all) but is very much aimed at the negotiation process, something that it would take an extremely brave or ignorant soul to claim is anything but chaotic and ongoing.

What reasonable mind – particularly one clever enough to hit CEO level in a multi-national corporation – could conclude that investing tens or hundreds of millions into a plant in the UK is a good idea when they have no sound basis for knowing what the outcome of negotiations – and thereby the standing on which they will realise those investments – will be?
