A rush at the pumps is expected at Asda in Canterbury this weekend after the company announced it was dropping the price of petrol to less than £1 a litre.

The supermarket is the first big retailer to react to a slump in world oil prices.

From tomorrow unleaded will cost 99.7p and diesel 103.7pp - a six-year low. But prices will rise to 101.7p and 104.7p on Monday.

Asda claims to be the only retailer that has a national price cap on fuel at all 277 filling stations.

Senior Petrol Director Andy Peake said: "For the second time this week we’re giving drivers a festive fuel boost and investing in a further price drop.

"We’re adding a further boost by investing in a three-day fuel price drop meaning drivers can now benefit from fuel as low as 99.7ppl in the crucial run-up to the festive period."

"We know our competitors are likely to follow but Asda don’t have a postcode lottery on fuel meaning no matter where customers live, they will benefit from the same fuel price at every single one of our filling stations.

Asda cut fuel to below £1 at the end of November and say it received strong feedback from customers.
