British supermarkets are imposing limits on how many salad staples shoppers can buy as supply shortages leave shelves empty of some types of fruit and vegetables. The disappearance of fresh produce is said to be largely the result of adverse weather leading to a reduced harvest in southern Europe and North Africa.

Shortly after Russia invaded Ukraine, the closely watched food price index of the UN Food and Agriculture Organization (FAO) reached its highest recorded level, stoking consumer prices across the world. In the UK, for example, the prices of many everyday items increased way ahead of inflation, with bread and eggs both up 18% in the year to December, and milk up 30%.

Food prices in the UK are at their highest for 15 years and something similar is happening in almost every country around the world.
