The OFT releases its report on the fuel sector this today.
Campaigners have called for the Office of Fair Trading (OFT) to launch a full investigation into the petrol market.
The OFT is to report today on the findings of a review it has been carrying out of how the sector operates.
The founder of campaigners FairFuelUK, Peter Carroll, said: “Tomorrow’s report by the OFT should call for a landmark full investigation into why the UK road fuel market is so dysfunctional with its regional variations, slow price falls, apparent market monopolies and pump prices that are measured in nine-tenths of a penny.
“There is a suspicion that some people are making a lot of money speculating in the petrol and diesel market that is essential for every family and business in the country.
“This needs to be fully examined and these suspicions addressed.”
The OFT launched a review in September into whether reductions in the price of crude oil are being passed on to motorists.
The UK retail road fuels sector is estimated to be worth around £32 billion.
