Mr. Sadiq Khan: My right hon. Friend is aware that the UK takes over the presidency of the UN Security Council in April this year. He will agree, I am sure, that global warming is a matter of international security. Will he therefore repeat the leadership role that we played when we held the presidency of the EU and G8 in 2005, and ensure that climate change becomes an agenda item for the UN Security Council for the first time in its history, which will demonstrate the urgency that the issue deserves?

David Miliband: My hon. Friend raises a very important point. The Foreign Secretary and I had dinner with the new Secretary-General of the UN in December, before he took up his post. It was extremely encouraging to hear the new UN Secretary-General pick up the mantle from Kofi Annan. One of the last things that Kofi Annan said as Secretary-General of the UN was that one of his biggest regrets was that in his 10 years in office, he had not put the main UN machinery at the heart of the battle against climate change. The suggestion that my hon. Friend makes is important. It is only through the UN and United Nations framework convention that we can have legally binding treaty obligations. All the work that is being done through the European Union, the Group of Eight and the Gleneagles dialogue is vital preparatory work, but in the end it must be in the UN forum that we make progress. My hon. Friend’s call is an important one.
