Supermarket inflation hit 8.3% in the past month, the highest rate in 13 years, adding £380 to annual bills as the rising cost of living weighs on families.

Sales fell at all the big supermarkets as shoppers switched to discounters Aldi and Lidl and bought more own-label goods in an effort to keep a lid on spending, according to the latest data from Kantar.
