Motorists have been hit with a rise in the price of petrol and diesel for the third month in a row, according to new figures.
The cost of filling up an average family car has increased by around £5 since the end of February, RAC Fuel Watch data for May revealed.
Unleaded rose by 1.92p per litre (ppl) in May to 108.67p, while diesel went up by 2.2ppl to 110.7p.
The RAC said the increase was driven by a 14% rise in the price of oil.
The organisation's fuel spokesman Simon Williams said:
Motorists will be disappointed to see pump prices going up again having enjoyed filling up their vehicles with petrol and diesel for under £1 a litre at the start of the year. The sub-£1 litre is now sadly starting to seem like a distant memory. Since the end of February the price of both unleaded and diesel has increased by around 9p a litre which has driven [up] the cost of filling up by around £5.
But he added that increased production in the Middle East could mean that prices will not rise much above current levels "for the time being".
