Morrisons has offered an explanation for a steep rise in petrol prices.
Drivers were furious after the St Helens store on Baxter's Lane raised its petrol prices twice in just three days. The prices were reported as 171.9p per litre on Friday, June 10.
This rose to 175.9p over the weekend before peaking at 180.9p by Monday, June 13. A rise of almost 10p in just three days, despite the government's fuel duty cut aiming to lower prices for petrol and diesel.
