Liberal Democrat Leader Ed Davey has called on Boris Johnson to haul petrol firm bosses into Downing Street, after research by the RAC found they have failed to pass on nearly half of the fuel duty cut to consumers.
The Liberal Democrats are also calling for an emergency VAT cut that would save the average family £600 a year.
Liberal Democrat Leader Ed Davey said: “This Conservative government is sitting on its hands and allowing petrol firms to rake in eye-watering profits at the expense of hard-pressed families.
“This government’s failure to tackle soaring prices of petrol and diesel is hitting our rural communities hardest. They need help now, instead we have a government in chaos that is raising taxes again and again.
“It’s high time Boris Johnson hauled petrol retailers into Downing Street to grill them on why the fuel duty cut hasn’t been passed on.
“Ministers need to act now to tackle this petrol profiteering and slash taxes to put money back into people’s pockets”.
