I agree that we do have to think very innovatively about it, because of the scale of the challenge—there’s no doubt about that. Innovation really does need to be central to our approach to meeting those challenges. Some of the models that you described I am familiar with, and I’ve asked officials to provide me with some more advice, because I do think that learning from best practice from other countries is something that we should absolutely be keen to do—as I would hope other countries can look to us in areas where we are performing well, as well.
