British motorists are grappling with unprecedented fuel prices as diesel has officially surpassed £2.00 per litre, marking a 33p rise since February. The average price for diesel on motorways now stands at 200.47p, while petrol has also seen significant increases, averaging 179.89p per litre. This surge follows turmoil in the Strait of Hormuz, a critical shipping route for oil and liquefied natural gas, leading to global supply constraints. Although a recent conditional ceasefire in the Middle East caused a temporary drop in Brent Crude prices by 14%, experts, including Simon Williams from the RAC, indicate that consumers should not expect immediate relief at the pumps. The long-term effects on Gulf oil production remain uncertain, and motorists are encouraged to find the best local prices to mitigate the impact of rising fuel costs.
