I could not agree more with the hon. Lady: we want to see the greatest possible transition, as fast as possible, to electric and hybrid vehicles for the future, but we have to be able to do it in a sustainable way. We have to ensure that electric vehicle technology, including batteries and other opportunities, moves with us at the same time. Other countries have moved faster than us, and I recognise the points the hon. Lady makes, but what is important is that we begin this discussion about how we can achieve that. There are a number of policy measures by which we can do it. There is also a supply-side as well as a demand-side issue when it comes to electric vehicle technology, and we need to be able to work on both sides of that economic argument in order to increase the number of electric vehicles on our roads. There are issues about charging points, which I also recognise. We need to do it in a sustainable and affordable way that ensures that we can continue a transformation of the economy.
