10:59 Mr Iain McKenzie (Inverclyde) (Lab)

As the hon. Gentleman will be well aware, the fuel duty escalator introduced by Labour was a green tax to put funds into green energy. Unfortunately, that idea has never been taken up. We heard from this Government that they were to be the greenest that we had ever seen, but they are not by some margin.

11:19 The Parliamentary Under-Secretary of State for Energy and Climate Change (Amber Rudd)

As we have discussed, movements in pump prices are driven by crude oil prices, and analysis by the Department of Energy and Climate Change suggests that, once crude price changes are converted into sterling, they are fully passed through into pumps within six to seven weeks, which largely represents the time required to refine crude oil into petrol and diesel, and to distribute petrol and diesel. Although we have already seen some price falls, I am hopeful that we may see more in the future, after the time lag of six to seven weeks.
