Sainsbury’s chief executive Mike Coupe has said major food suppliers to UK supermarkets should take the hit from a devalued sterling, rather than passing on any price increases to UK retailers and shoppers.Since the Brexit vote in June, the sterling has been extremely volatile and weakened to above £0.90 against the euro at one point. The UK currency has also hit 30-year lows against the US dollar. This sharp depreciation in the sterling has forced a number of large food brand owners, such as Unilever, Pepsico and Birds Eye, to demand price increases for their products on UK retail shelves.
