Question to the Department for Business, Energy and Industrial Strategy:
To ask Her Majesty's Government what assessment they have made of the causes of the disparity in diesel and petrol prices at filling stations across the country.
The Department’s analysis shows that retail prices of petroleum products such as petrol and diesel are primarily driven by the underlying price in the global market of crude oil and by exchange rates. Departmental analysis shows that changes to the price of crude oil feed through to retail prices over the course of 6-7 weeks.
