UK supermarket supervisors have been called to meet with the government to address the scarcity of tomatoes, cucumbers, and peppers after five major supermarkets, including Tesco, Sainsbury's, and Asda, needed to ration purchases. This shortage is attributed to adverse weather conditions in Spain and north Africa, which have disrupted harvests, and the economy-related inactivity of many UK greenhouses. Lidl has also joined in imposing purchase limits. The situation is part of a broader European problem, with the UK experiencing the most severe shortages. The government aims to investigate how to prevent such incidents in the future, sparking discussions on Brexit's potential role and the possibility of competitive pricing influencing supplier decisions.
