Asda signalled a likely supermarket petrol price war today by cutting its pump prices by 2p a litre.

The reductions will take effect from tomorrow, with Asda motorists paying no more than 131.7p a litre for petrol and 137.7p a litre for diesel.

Asda petrol trading director Andy Peake said: "Today's move shows that we are once again leading the way in reducing the price at the pump.

"Unlike other retailers, our price cuts benefit everyone across the country, meaning that no one filling up at Asda will be forced to play a postcode lottery."
