The full horror of what has happened in the United States earlier today is now becoming clearer. It is hard even to contemplate the utter carnage and terror which has engulfed so many innocent people. We've offered President Bush and the American people our solidarity, our profound sympathy, and our prayers. But it is plain that citizens of many countries round the world, including Britain, will have been caught up in this terror.

As so often before, on the courage and determination of British men and women, serving our country, the fate of many nations rests.

There is no meeting of minds, no point of understanding with such terror. Just a choice: Defeat it or be defeated by it. And defeat it we must.

As I have said throughout, I have no doubt that they will find the clearest possible evidence of Saddam's weapons of mass destruction.

Leaders lead but in the end it's the people who deliver.

All the evidence here, for example, in Britain, is that migrants, particularly from the rest of Europe, who come here contribute far more in taxes.

We need to develop the new green industrial revolution that develops the new technologies that can confront and overcome the challenge of climate change; and that above all can show us not that we can avoid changing our behaviour but we can change it in a way that is environmentally sustainable.
