Finance Bill

I am grateful for that intervention. I should declare an interest, in that my car has a diesel engine. Until about a year ago, I paid about 1p or 2p more per litre but—and this follows on from a point made in the previous speech—the greater fuel efficiency of diesel meant that the mileage was greater and that the cost differential was almost zero. The cost of diesel is quite a lot greater now, as a result of higher demand and restricted refining capacity. However, that prompts questions about whether the Government should introduce additional incentives for people to switch to diesel-fuelled cars, and that is territory that I do not intend to venture into in this speech
