Steve Clarke, group marketing manager for The Fuelcard People, commented: "It made headlines that the UK is back into the world 'Top Ten' for petrol prices, but nobody seems to have noticed the diesel chart. Of more than 170 countries surveyed, we have the world's most expensive diesel."
Explaining why diesel prices are so high, Clarke said: "Each nation buys oil on the same global markets, but then imposes its own taxes. The price on our forecourts includes 59 per cent for diesel, 61 per cent for petrol. Having to pay the highest fuel duty in Europe is crippling our economy and hindering the recovery."
High diesel prices mean UK businesses are "trying to compete internationally on a very uneven playing field", Clarke said.
