It is now clear that the policy of phasing out the production of petrol and diesel cars will have an impact on employment in some areas of the United Kingdom where we have higher than average unemployment. What impact assessment have the Government done on the effect of this policy on revenue from fuel duty? What impact assessment have they done on the environmental impact of the mining of earth metals, one of the dirtiest industries in the world? What impact assessment have they done on the impact on poor families who will now face higher capital costs when it comes to purchasing cars? Would it not be a far more Conservative policy to allow manufacturers and consumers to make the choice as to which cars they make and which cars they drive?
