Asda's 3p a litre fuel cut has sparked a petrol price war among its 'big four' supermarket rivals.
It announced yesterday that it is capping its petrol prices at 110.7p per litre, with diesel at 112.7p from today.
These cuts were swiftly followed by Tesco cutting petrol and diesel prices by up to 3p per litre yesterday afternoon, and Morrisons and Sainsbury's making similar announcements.
The cost of fuel had already fallen slightly last week, bringing to a halt the recent steep rises.
Before the supermarket announcements, Government figures showed that average fuel prices had reached their highest level since July last year, with motorists being charged 116.6p per litre for petrol and 119p per litre for diesel.
