Shoppers have witnessed their grocery bills surge at the fastest rate since 2008 following spikes in the price of butter, milk and chicken, according to new data.
Research firm Kantar has revealed grocery price inflation jumped to 11.6% for the four weeks to August 7, compared with 9.9% in the previous month. It said this equates to a £533 annual increase in the average UK household's grocery bill.
As a result, it reported sales of own-label value products increased by almost a fifth - 19.7% - as shoppers sought to make savings.
