According to the RAC, the average price of petrol reached an Iran war peak of 159.53p a litre on 28 May, while diesel’s highest average price during the conflict was 191.54p a litre on 15 April.

Since then, prices have tumbled. Over the month of June, the RAC said the average price of diesel sank from 183.75p a litre to 167.14p a litre.

The average price of petrol dropped from 159.37p a litre to 151.40p a litre over the same period.

However, the RAC said prices are still much higher than before the conflict began when average petrol prices were 132p a litre and average diesel prices were 142p a litre.

The RAC’s head of policy, Simon Williams, said: “As things stand, petrol should dip under 150p soon and diesel ought to get to below 160p, but we would need the price of oil to fall further to see a return to the pre-conflict prices.”
