As I said earlier, where a particular bus or public transport service is in difficulty, much the swiftest way is for it to be dealt with specifically with the oil supplier and, if necessary, with the Department. Where the hon. Gentleman is at fault, or perhaps has not received the right information, is in implying that all bus and public transport services are in grave difficulties and that they should all become an essential priority. That is not so. A general categorisation and preference for those would merely divert petrol, oil and diesel from farm tractors, from people trying to drive to work over the mountains in Wales and from others who are doing work just as valuable in our economy as those driving buses. The hon. Gentleman must understand that a fair share of the cutback of 5 per cent. has to be borne by all those using oil and oil products, but, of course, we must give priority to the emergency services. That is the commonsense way.
