All I can assure the hon. Gentleman about is that as far as by-elections are concerned—[Interruption.] I am absolutely certain that in the climate of the Middle East crisis there would be no handicap to any Government announcing measures to restrict, allocate, or ration petrol. This would be perfectly acceptable. I must point out that no country in Western Europe has introduced oil rationing as yet. Nor has the United States. The only restrictions put on by any Government in the western world have been the Dutch restrictions upon Sunday motoring, which would make a minute impact on total oil resources. The Government are not alone in being wise and prudent enough to watch the situation carefully. Where we are alone is that we have much better reserves than most other countries.
