Experts are warning that the UK is on the brink of a food crisis, exacerbated by extreme weather conditions, inflation, and the ongoing war in Iran. A letter signed by food experts, including Mike Barry, former director of sustainable business at Marks & Spencer, urges the Labour Party government to update the national food strategy to address these escalating challenges. The volatility in food supply across major supermarkets like Tesco, Sainsbury's, Asda, and Morrisons is now seen as the 'new normal'. Tim Lang, a food policy professor, emphasized the need for government action on food security, stating that the public is ready for change but requires leadership. Richard Nugee, a retired general, highlighted the potential for reduced food quantities due to climate impacts and geopolitical disruptions, warning that the inability to afford food could lead to significant societal stress. The experts stress that ensuring food security is a critical state responsibility, especially in light of these challenges.
