Energy secretary Grant Shapps will meet heads of major supermarkets and petrol firms over fuel prices, after an investigation found drivers paid an extra 6p per litre for fuel last year.

Shapps is set to meet bosses from Asda, Tesco, Morrisons, Sainsbury’s and other major fuel retailers today, who will be “held to account for any failure to pass on savings to consumers”.

Supermarkets have until the end of August to share live fuel pricing information with the Competition and Markets Authority (CMA) in order to maintain transparency and improve competition.

Retailers that fail to comply will be forced to share their prices said the Department for Energy Security.

This comes after supermarkets were accused of profiteering following a report by the CMA found drivers paid an extra 6p per litre for fuel last year.

In an article for The Sun, Shapps said: “On Monday, I will be calling in the bosses of Asda, Tesco, Morrisons and Sainsbury’s – as well as the likes of BP, Shell and Esso – to explain themselves.

“I want to hear how they are going to fix this. I will be telling them to do the right thing and immediately end any attempt to overcharge at the pumps.

“I will demand that these companies sign up to the CMA’s scheme this summer to hand over their pricing information so that fuel comparison apps and websites can help consumers compare local fuel rates more effectively.”
