Supermarket giants Asda, Tesco and Sainsbury's will be selling a litre of diesel for less than £1 from today.
Asda was the first to slash prices with a 3p per litre cut on diesel at its 279 stations. Tesco said it would also be dropping the price of diesel to 99.7ppl at all of its 500 filling stations.
Sainsbury's also said its diesel would cost 99.9 pence per litre across its 301 forecourts.
The RAC said the price cut was good news for drivers, particularly after the expense of the festive season, but it was long overdue.
Diesel drivers will clearly welcome this move by the big supermarkets, although it would be fair to say it has been slow in coming. The wholesale price of diesel has been around two pence cheaper than the wholesale price of petrol since a couple of weeks before Christmas so we should have seen these cuts earlier and that is what the RAC has been calling for... The focus has been on the price of petrol but with more diesel sold in the UK the retailers should be more transparent and reflect the savings they are making in the wholesale price more swiftly at the pump. And right now diesel is cheaper than petrol. >
