Supermarkets in Britain are experiencing supply issues that have led to the rationing of some fruits and vegetables, with chains like Aldi and Tesco facing shortages of certain vegetables. The problem is due to poor harvests caused by bad weather in North Africa and Spain. Other supermarkets such as M&S, Sainsbury's, Iceland and Co-op are also affected. The British Retail Consortium has confirmed the issue and assured the public that retailers are working to resolve it.
