MORRISONS are starting a pre-Christmas fuel price war, slashing the cost of petrol below £1 a litre.

However, in order to get the lower price customers will have to spend £50 in store.

Over the weekend, the company reduced the price of unleaded to a maximum of 109.9p at its 333 forecourts.

From Monday, those who have spent £50 in store will be able to fill up for 99.9p when they present a voucher.

Morrisons says it is making the cuts "to help motorists with the cost of getting around during the pre-Christmas shopping spree, including Black Friday".

Roger Fogg, Morrisons' Services Director, said: “With Christmas around the corner, our customers tell us they very much welcome our help in reducing the cost of their fuel. That’s why we are turning the clock back to the start of this year when petrol prices were typically below £1-a-litre.”

The offer will run from November 21 to December 3.
