Gianluca de Ficchy, the Japanese firm's Europe chairman, said that the decision had been taken for "business reasons" affected by rules on diesel engines and reduced sales.

The announcement that the X-Trail would be built in Japan was made in a letter to staff that followed a day of political rows between Brexit supporters and opponents over the reason for one of Wearside's largest employers reneging on a 2016 decision to build the car there.

In the letter Mr de Ficchy said: "Today's announcement will be interpreted by a lot of people as a decision related to Brexit.

"We have taken this decision for the business reasons I've explained but, clearly, the uncertainty around the UK's future relationship with the EU is not helping companies like ours to plan for the future."

I prefer the stated reasons given by Nissan's Gianluca de Ficchy, the Japanese firm's Europe chairman.
obviously brexit creates uncertainty but he gives 3 clear reasons for retaining manufacture elsewhere,
1)The investment required would be considerable.
2)Actual and impending legislation on diesel engines
3)Delining sales

It is newspapers and the union attributing the sole reason to brexit.
I prefer to believe the information given first hand by the company that made the decision.

The Herald six hours ago using my same data comes out with the following headline:
Nissan chief attacks 'Brexit uncertainty' as company confirms new vehicle will be built in Japan not UK.

If that headline has not been spun to the point of being outright lies then tell me what I have misunderstood.

You must point what you mean by invective.(insulting, abusive, or highly critical language.)
I will accept highly critical, but I would regard that as a compliment given for well researched responses.
