The UK languishes near the bottom of a ranking of European countries for measures taken to ease the burden of high fuel prices.
The UK government is 12th out of 13 European countries to have cut petrol taxes since prices started to soar in March, according to the RAC.
However, 15 other European governments have not reduced the gas tax at all.
The Republic, which has reduced petrol tax by 14.5 pence per litre, is 5th on the table.
The 5p per liter reduction implemented by the UK in March is dwarfed by fuel tax reductions enjoyed by drivers in countries such as Germany (25.1p per litre), Italy (21 .2p per litre), Portugal (16.2p per litre) and the Netherlands. (14.7p per litre).
The French and Spanish governments have introduced forecourt cash rebates worth around 15 pence per liter and 17 pence per liter respectively.
Some fuel retailers, including TotalEnergies in France and BP Spain, have price reductions of up to around 33p per litre.
UK petrol prices have finally started to fall in recent days after pressure on retailers to reflect a drop in wholesale costs that began seven weeks ago.
But the UK still has an average petrol price 186p per liter higher than all EU members except Finland (190p) and Denmark (also 186p).
Drivers in France pay around 23 pence per liter less than those in the UK.
The situation is similar for diesel, with only Croatia introducing a lower fuel tax reduction than the UK, and only one EU member, Sweden, having a higher average price.
RAC fuel spokesman Simon Williams said: “This analysis lays bare an uncomfortable truth for the UK Government – that compared to other European countries it is about the least done to support drivers during the current period of record fuel prices.
“The result is that the UK is one of the most expensive places to refuel and puts it above other countries that have historically charged more fuel than UK retailers, including France and the UK. Netherlands.”
