The cost of food including beef mince, oranges, cheese and cucumbers will go up from the start of next year if the UK fails to agree a trade deal with the EU, retailers have warned.
The British Retail Consortium said prices of clothes, footwear and furniture are also likely to rise, as tariffs are placed on a broad range of imported goods.
Poorer households will be hit hardest as they spend a higher proportion of their incomes on essentials which will become more expensive without tariff-free access to the Continent, the BRC said.
