03 Apr 2019 --- Global commodity prices and weather events pushed up UK food prices in March, according to the latest figures from The British Retail Consortium-Nielsen Shop Price Index. Increases in global cereal prices drove up bread and cereal prices, while bad weather during 2018 negatively impacted yields of several UK crops, including onions, potatoes and cabbage. As a result, these products are now seeing significant price inflations. But experts warn a bigger issue still for British shoppers are uncertainties surrounding Brexit.
