Basics such as butter, milk and poultry show biggest increases in figures from market research group
Supermarket bills in Great Britain will soar by £533, or more than £10 a week, as grocery price inflation hits its highest level since at least 2008.
The price of a weekly shop rose 11.6% in the four weeks to 7 August, compared with a year before, according to the latest figures from Kantar. That represents the highest rate of inflation since the market research group began tracking the sector 14 years ago.
