I thank the right hon. Gentleman for his question. He is one of those Members of this House I always listen to with great care and interest, and he has a track record on these issues as well as on financial issues and many others. I made this point in my opening remarks that we have to be careful about this artificial dividing line between what serves our moral sense of duty and what serves a harder, grittier perception of the national interest. I think that that is an artificial dividing line. I believe in a sense of moral self-interest, an enlightened self-interest, and if he looks at what we are doing on vaccines at the Gavi summit, he will see that that will crystallise the opportunity for us to do things that serve the people of this country, by securing a vaccine, while helping the most vulnerable in the world.
