Having won the battle of the Marmite jar with his erstwhile employer Unilever, Mr Lewis has issued a warning to other suppliers who might be tempted to use Britain’s Brexit weakened currency as an excuse to raise prices. Mr Lewis has suggested that suppliers wouldn’t make customers in other countries pay extra for temporary periods of currency weakness, and so the same should be true for Brits. Good PR is something Tesco could do with in the wake of the Tesco Bank cyber fraud and with the Serious Fraud Office nearing the end of a long running investigation into the black hole in the retailer’s accounts prior to Mr Lewis joining. Personally I’d be a little more willing to believe the Tesco-man hype were Mr Lewis to make some similarly punchy public statements about the subtler ways multi-nationals have been sneaking through price rises, via the deflation in the sizing of their products.
