Shoppers at major supermarkets Asda, Morrisons, Tesco and Sainsbury’s could be spending up to £5 more when buying a tank’s worth of petrol or diesel, according to new analysis.

This increase in price comes as the value of the pound decreases.

AA fuel price spokesman Luke Bosdet said: “The influence of the exchange rate is often overlooked when drivers compare oil price movements with those at the pump.

“At the moment, it is critical. Oil and fuel on commodity markets are traded in dollars, which makes the weaker pound very bad news for motorists.

“The price of oil is back to the level at the start of the Ukraine war but petrol is 15p a litre more expensive.

“Two-thirds of that higher cost is down to the weakness of the pound.”
