No. I entirely reject the hon. Lady's suggestion. I do not think that there is any foundation for it at all. When we revised our commitment just a few weeks ago and committed ourselves to bringing down emissions to 1990 levels by the year 2000, we made it clear that we would do that if other countries took similar action. It is important to appreciate that this is a global problem which requires a global response. It is as important to secure multilateral, rather then unilateral, action in this matter as it was in respect of disarmament, when the stand taken by Her Majesty's Government proved to be effective, in contrast to the stand urged upon us by the Opposition.
