In support of my right hon. Friend’s case, that defining “exceptional circumstances” is very difficult and is not defined in the amendment, I refer to the example given by the right hon. Member for East Yorkshire. Sheffield suffered large job losses due to the closure of steel plants back in the early 1980s—no thanks, let me add, to the policies of the Conservative party when it was in power. In fact, the impact on car ownership would have been very low at that time because many of the steelworkers would not have owned cars. The lowest levels of car ownership in Sheffield were in the steelworking areas. The variations according to local circumstances would have benefited the citizens of the south-west of the city where levels of car ownership were high and where job losses were at a minimum. In fact, I do not think that the example works to justify the amendment.
