Fuel retailers were accused of “rocket and feather” pricing after new record petrol and diesel prices over the weekend.
Petrol hit an average of 191.1p a litre on Sunday, while diesel flirted with the £2 level at 199.1p Saturday, according to Experian (LSE:EXPN) Catalist data.
The unleaded figure was a shock to the RAC, which had anticipated a fall, and it insisted fuel retailers have been fast to pass on higher costs but reluctant to react to falling wholesale prices.
Simon Williams, RAC spokesperson, commented: "We are struggling to see how retailers can justify continuing to put up their unleaded prices as the wholesale cost of petrol has reduced significantly.
"This is sadly a classic example of rocket and feather pricing in action, and one which the Competition and Markets Authority (CMA) will no doubt be looking at very closely.”
Although it is unknown when the result of the CMA’s market review will be.
"Ultimately, the longer they hold out, the more they benefit and the longer the misery continues for drivers struggling with the high prices," Williams added.
Fuel retailers have failed to respond, but have previously repeatedly denied accusations of profiteering.
The AA, which is the UK’s other main motoring body alongside the RAC, also displayed its concern on the matter and called for urgent action.
Its president, Edmund King, said: "The government needs to urgently take action on price transparency and cut duty levels."
