The average cost of filling up a family car has surged to as much as £100, as pump prices continue to climb amid the ongoing war in Iran. Petrol and diesel prices have both hit new post-war highs, squeezing motorists just as millions of Britons take to the roads for their summer holidays, and adding to calls for the Labour government to abandon a planned rise in Fuel Duty.

Average petrol prices have reached a new post-war record, with a full tank now costing £89, while diesel has climbed to £100 for a typical family car. This compares with £73 for petrol and £78 for diesel before the conflict began, marking a sharp jump in costs. The prolonged war in Iran is being blamed for driving fuel prices higher, intensifying pressure on ministers to scrap the forthcoming Fuel Duty increase.
