@Blue Hills @Pale Rider - thank you. The concern, well thought really, in my mind is fresh food supplies. It seems this terrible situation is going to last for a long, long time. I spent my working life in horticulture and know and understand the intricacies of moving fresh produce from production site to market. It was, for me, a main plank of reasons to remain in the EU.
We import 50% of our food, 30% from the EU, and I'm concerned about the situation in, say, 2-3 months time. Trucking tomatoes from Spain to the UK will be interesting - presuming someone picks them.
I'm fortunate to have a large allotment. I'm looking hard at my plans and how I shall vary them.
