The average price of petrol rose to 191.05 pence on Sunday, while diesel hit a record high on Saturday at 199.09 pence before edging down a day later, according to the RAC.

This was the price at the pumps in Shell at Westfield on Thursday June 23.

RAC fuel spokesman Simon Williams was quoted as saying : "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,"
