The UK is experiencing a fresh food shortage, with supermarkets limiting purchases of tomatoes, cucumbers, lettuce, and broccoli due to supply issues caused by abnormal weather in Europe and Africa. The situation is expected to persist for the next two to four weeks. The shortage is due to crop damage in Spain and Morocco, a decrease in greenhouse crop cultivation in the UK and the Netherlands, and Brexit. However, retailers and importers in the UK say that Brexit is not the main cause of the crisis.
