Asda, Tesco, Sainsbury’s and Morrisons to explain why they have failed to pass on savings to customers

Supermarket bosses will meet Grant Shapps on Monday after the energy secretary pledged to hold “rip-off retailers” to account for charging motorists “sky high” prices for fuel.

Executives from Asda, Tesco, Morrisons and Sainsbury’s – as well as those from the fuel providers BP, Shell and Esso – will come under pressure to explain why they have failed to pass on savings to customers after a drop in their own wholesale fuel costs.
