I thank my hon. Friend, who stands up so well for her constituents. She is right that the UK cannot do everything on its own, but we can set a powerful example. We have significant capabilities that we can bring to the field and a powerful example that we can set. That is the approach we intend to take. Leadership comes from doing the right thing, and I am confident that we can expect the trend we have already seen, of other nations following our lead, to continue.
