Diesel prices in the UK have reached an all-time high, averaging £2 a litre, according to the RAC motoring group. This surge comes as petrol prices are also on the rise, exacerbating financial pressures on drivers across the nation. The record diesel cost is attributed to global factors impacting oil prices and supply chains. This increase will significantly affect businesses reliant on diesel, such as haulage and agriculture, potentially leading to higher costs for consumers. Experts warn that the rising fuel prices contribute to broader inflationary pressures within the UK economy. The situation is prompting calls for government intervention to alleviate the burden on motorists and businesses.
