Fuel prices at the pumps have reached a record high, with diesel breaking the £5 a gallon mark.
Average petrol prices have now reached 104.85p a litre compared with just 87.27p a litre a year ago, according to latest figures from the AA.
And diesel has soared to a record average price of 110.31p a litre, compared with 91.09p a year ago.
In gallon terms, this means diesel has now passed the £5 mark, the association said.
It now costs £8.79 more to fill a typical 50-litre fuel tank than a year ago.
An average car owner is now spending £18.84 more per month on petrol.
AA president Edmund King said: "The £5 gallon must surely concentrate minds at the Treasury and should be a warning to the Chancellor that his proposed increase of 2p per litre should not go ahead in the Budget next month.
"The Chancellor must accept that global oil prices are soaring out of control so he should not add fuel to the fire by hiking up the tax. Rural motorists, the disabled and car-dependent communities are suffering enough."
"In one week, the UK price of petrol has shot up a penny and diesel even more. At the same time, market commentators have reported a gasoline glut in the US, enabling them to sell cut-price fuel to Nigeria.
"Drivers in the UK are asking why their car fuel prices are soaring while petrol is being offered at a discount elsewhere."

I put 25 quid in and the needle didn't even get half way...just one of 'those' moments when you question so much...car dependence, oil dependence, prices, cash being king, tapped out credit...as RFD stated yesterday we're three meals from anarchy, but folk will fight with each other, not the 'systems', or increasingly heavy handed govts that led us down this path
And to think that the price of a pint (sorry - Carlsberg, not milk) is £2.50 minimum (N Wales) - not that really is enough to start a riot over!!!
