Major supermarkets have been criticised for charging more for petrol in less well off parts of the Valleys than in Cardiff. We found unleaded on sale at prices between 3p and 6p a litre higher in towns in Rhondda Cynon Taf and Merthyr than in Wales' capital.
The leader of RCT council, Andrew Morgan, has called on Asda and Tesco to explain the difference in price between areas that are so close in distance. He wrote on Twitter: "Can you explain @asda @Tesco why your petrol and diesel prices are higher in the Valleys than other areas of south Wales? It seems the poorest areas that are more car dependant have the higher prices? Be good for an explanation please?"
He said the apparent price differences made him feel uncomfortable as Valleys communities historically have less disposable income than those closer to major city centres. He said it would undoubtedly have a knock-on impact on Valleys town centres, as people spend more on fuel and less on local businesses.
