I am grateful that the right hon. Gentleman is devoting some of his time to the important issue of humanitarian aid. Does he agree that my right hon. Friend the Secretary of State for International Development has given a tremendous lead, but that, as in other areas, if we act unilaterally we cannot solve all the problems that we want to solve? Because of their commitment, the Prime Minister and my right hon. Friend the Secretary of State are in a strong position to ask the rest of the world, especially the nations in the coalition, to make the same humanitarian contribution as we do—and that is just as important as addressing the problems that we are discussing today.
