Even here at the bottom end it's a mess
We do forklifts; selling, hiring and maintaining. All very unglamorous and dealing almost entirely with the manufacturing industry.
Our main supplier of parts is in Belgium, our (separate) main supplier of new machines is also in Belgium, our biggest single customer is German and some huge proportion of our business trickles down from [unnamed motor manufacturer].
So, our major suppliers due to exchange rates became 6% more expensive overnight, our single biggest customer's future in the UK is uncertain, and heaven only knows what the carmaker will do now. Oh, and if (as anyone remotely sensible wants) the UK is to retain access to the common market we'll still be required to adhere to all the EU regulations, but without having a vote in them.
Yay independence?
