The AA has called on Finance Minister Brian Cowen to take it easy on motorists when he announces his Budget later today.
The Minister is expected to increase taxes on motor fuel, but AA spokesman Conor Faughnan said this would be unfair as motorists were already paying too much.
"The last Budget involved an [increase in] excise duty on petrol and diesel and that wound up hitting motorists hard during the year," he said.
"In fact, because of the rise in the price of oil, the petrol prices went up by 18% in the course of the last year, so at the very least, let's have no further increases in petrol prices. In fact, we'd be well served by a reduction."
