Petrol prices could fall as much as £10 in the next two weeks, according to AA. Prices have fallen from record highs seen in recent months driven by the war in Ukraine and sanctions on Russian oil.
Luke Bosdet, the firm's fuel price spokesman, says the fall in price could follow. He said: "Wholesale petrol's trajectory, if sustained, would lead to savings of a tenner off a tank from the record highs, providing the fuel trade is prepared to pass them on," he said.
The average pump price is now down to 188.76p a litre for petrol and 196.96p a litre for diesel - a drop from the start of the month when petrol cost 191.53p a litre and diesel was 199.07p a litre.
"The problem is that, in many places, the price cuts are quite simply not happening despite more than six weeks of falling costs," said the spokesman, LeicestershireLive reported.
"Roads may suffer extreme heat today and tomorrow but pump prices should have cooled off much more significantly by now."
Lib Dem MP Jamie Stone said people living in rural parts are facing far higher costs than others in more urban areas. Liberal Democrat analysis shows households in rural areas can pay £114 a week in transport costs - nearly £40 more than those living in towns and cities.
Accusing the UK Government of "refusing to lift a finger to help", Mr Stone demanded action from the five Tory MPs who are fighting to become the next prime minister. The Liberal Democrats want rural fuel duty relief to be doubled to 10p a litre, as well as claiming the scheme should be "significantly expanded" to cover more areas.
The party also wants an emergency cut in VAT, reducing the charge from 20 percent to 17.5 percent.
