I am grateful to the hon. Gentleman for his remarks. I can go one better than he suggests. In his statement to the House on Monday, my right hon. Friend the Prime Minister said that he would write to the other countries in the European Community and to the other G7 countries proposing a follow-up to the conventions that were signed at Rio. The hon. Gentleman can be assured that my right hon. Friend the Prime Minister and the Government in general will continue to take a lead in these matters.
