The average cost at the pump is now around £1.30 a litre, but the petrol itself only accounts for around a third of that. Fuel duty at 59p, plus VAT, means that the rest - no less than 62.5% - is tax, filling up the government coffers nicely, with fuel duty alone bringing in more than £26bn annually.
After mounting pressure from incensed drivers, the Treasury is considering scrapping another 1p increase, due next month. It is also pondering whether to introduce a price stabiliser, which would cut tax as pump costs rise. That might stop the prices fuelling around.
