It is important for these price reductions to be passed on. The Office of Fair Trading has investigated these concerns. In January 2013, it published its analysis, and Government analysis suggests that crude price changes are passed on to pump prices within about six or seven weeks. National average pump prices are now at their lowest levels since December 2010, but it is, of course, quite right to keep up the pressure to ensure such reductions are passed on. My hon. Friend will also be aware that, thanks to the policies of the Chancellor of the Exchequer, pump prices are nearly 20p a litre lower than they would have been under the last Government’s fuel duty plans.
