I know we're not allowed to talk about the January transfer window and its impact on the season to come, but it's a bit like ignoring the chief reason why we haven't got any tomatoes in Britain and the rest of Europe has.
Brexit?
I couldn't possibly comment.
Nothing to do with Brexit, everthing to do with the supermarkets only offering les than the cost of production to UK protected edible farmers. They just didn't plant very much as energy and fert costs are too high to justify what was on offer as forward purchase price.
Imports from Spain are cheap as they can grow without heat, normally UK farms put in about 5-10% but most have not planted until it warms a bit and the glasshouse heatimg costs come down. That means a squeeze on total availability. Also poor crop in Morocco has led to restricted exports from there.
Potatoes will be scarce later this year as half of Europe cut it's acreage due to low prices on offer.
