Last month, market leader Tesco TSCO.L said food inflation had peaked and all of Britain's major grocers have cut the prices of some products in recent weeks. Market researcher Kantar said annual grocery inflation was 14.9% in the four weeks to July 9, falling 1.6 percentage points from the 16.5% in its June data set. Over the 12 weeks to July 9 German owned discounters Aldi and Lidl were again the fastest growing grocers, with sales up 24.0% and 22.3% respectively, partly due to new store openings.
