My hon. Friend makes a good point. As in some other sectors, such as malaria, where the commercial models are not as well developed or as clear, there is a role for the Government, which is why we have set up the strategy and the partnerships. By de-risking and supporting the deep science in the early stages and bringing forward these partnerships of support, we hope to make it a sector in which more and more companies are beginning to see a return, and then they will start to invest their own money. All the indications are that that is beginning to happen here in the UK.
