Been giving some thought to this today, whilst delivering a van full of parcels from all over the globe. I get a delivery of 1/2 dozen sacks at about 8.00am, trucked overnight from a London hub, then sorted by a largely foreign workforce at the Bristol depot.
So if we have a hard brexit, will every single trade agreement need to be in place the next day to allow the seamless import of said goods into Heathrow? Or into Amazon UK hubs?
And if not, what will happen?
Not sure anyone really knows mate. To give you an example though, people had two years to prepare for GDPR and it still managed to trip up a good few organisations. Multiple that over many more regulations with much less lead time and I can't say I'm that optimistic that the transition will be a smooth one.
