RAC technical director David Bizley said the allegations were "worrying news for motorists" who are already suffering due to the high cost of keeping a vehicle:
The Office of Fair Trading inquiry concluded at the end of January that the UK fuel market was operating fairly and not against the best interests of motorists, and therefore that a Competition Commission investigation was not needed.
Motorists will be very interested to see what comes of these raids. Whatever happens the RAC will continue to campaign for greater transparency in the UK fuel market and for a further reduction in fuel duty to stimulate economic growth.
