UK motorists are being charged the highest diesel prices in Europe, according to new analysis. The RAC, which carried out the research, said there is “no good reason” why British fuel retailers are not cutting pump prices. It found the average price of a litre of diesel at UK forecourts is 155p. That is 5p more than Ireland and Belgium, which have the continent’s joint second most expensive diesel at 150p per litre. Even with the 5p per litre cut in fuel duty in spring 2022, the UK has Europe’s joint highest rate of duty on diesel with Italy at 52.95p per litre, but Italy’s average pump price is 7p per litre cheaper at 148p. France’s duty rate is the equivalent of just 1p per litre lower than in the UK, but its average price for diesel is 9p per litre cheaper at 146p. The analysis is based on figures from the European Commission and the UK’s Competition and Markets Authority. Government figures show diesels make up around a third of all cars licensed for use in the UK – 11.4 million. The vast majority of commercial vehicles such as vans and lorries are also powered by diesel. RAC fuel...
