I've talked to the motor trade industry, and it was very interesting. They told me, well before this got to this stage, that this wouldn't work. They came out with some suggestions. The big suggestion from them was to ensure that we tested vehicles for their emissions at source every year when they go through their warrant of fitness and ensure that those vehicles meet those standards. They also mentioned cash for clunkers. I'm not sure I agree with that one. But, however, those are at the other end of the market than where the Labour Party is focused on.
