I have resigned from the cabinet because I believe that a fundamental principle of Labour's foreign policy has been violated. If we believe in an international community based on binding rules and institutions, we cannot simply set them aside when they produce results that are inconvenient to us.
I cannot defend a war with neither international agreement nor domestic support. I applaud the determined efforts of the prime minister and foreign secretary to secure a second resolution. Now that those attempts have ended in failure, we cannot pretend that getting a second resolution was of no importance.
In recent days France has been at the receiving end of the most vitriolic criticism. However, it is not France alone that wants more time for inspections. Germany is opposed to us. Russia is opposed to us. Indeed at no time have we signed up even the minimum majority to carry a second resolution. We delude ourselves about the degree of international hostility to military action if we imagine that it is all the fault of President Chirac.
The harsh reality is that Britain is being asked to embark on a war without agreement in any of the international bodies of which we are a leading member. Not Nato. Not the EU. And now not the security council. To end up in such diplomatic isolation is a serious reverse. Only a year ago we and the US were part of a coalition against terrorism which was wider and more diverse than I would previously have thought possible. History will be astonished at the diplomatic miscalculations that led so quickly to the disintegration of that powerful coalition.
Britain is not a superpower. Our interests are best protected, not by unilateral action, but by multilateral agreement and a world order governed by rules. Yet tonight the international partnerships most important to us are weakened. The European Union is divided. The security council is in stalemate. Those are heavy casualties of war without a single shot yet being fired.
