bronwen, some people would say this is quite a brave bit of policymaking by the government, but presumably in the run—up to deciding to lift these restrictions, it will have factored in the evidence coming from scientists that there would be a third wave in the summer? you'd like to think so. i think this one is being driven by notjust politics, but the sense that the prime minister really wants to get the economy open. but it is an unusual thing, brave is a way of putting it, to be opening up atjust the point when cases are surging, albeit from a low level. and the world is looking to britain with astonishment, but also to see what happens with this experiment, which is really an experiment about whether the vaccines can break the pattern of the past, whether enough people are vaccinated to mean that the surge doesn't really take off. so in a sense, you can argue that england is, whether it intends to or not, doing the world a huge favour
