Motoring experts say drivers have "a right to know" why they are still being charged record prices to fill up their vehicles.
Figures from data firm Experian show the average price of a litre of petrol at UK forecourts reached a new high of 191.2p on Tuesday. Meanwhile, the average price of diesel was 199.0p per litre, just below the record of 199.1p per litre set on Saturday.
Simon Williams, RAC fuel price spokesman, said: "Inexplicably, fuel prices rose yet again yesterday. We can see absolutely no rhyme or reason why average forecourt prices are still going up, given that the wholesale price of both fuels has been falling for weeks.
