I will give way in a moment.
Doctors and nurses could be forced to make impossible choices about which patients would live and which would die, who would get oxygen and who could not. I know that some Members, like my hon. Friend the Member for Bexhill and Battle (Huw Merriman), are hearing from their local hospitals that the pressure is not that great yet, but the whole point about a national health service is that when hospitals in one part of the country are overrun, sick patients are transferred to another, until the whole system falls over. Let me be clear that this existential threat to our NHS comes not from focusing too much on coronavirus, as is sometimes asserted, but from not focusing enough, because if we fail to get coronavirus under control, the sheer weight of demand from covid patients would not only lead to the covid casualties that I have described, but deprive other patients of the care they need. We simply cannot reach the point where our national health service is no longer there for everyone.
This fate is not inevitable. We are moving to these national measures here when the rate both of deaths and infections is lower than they were, for instance, in France, when President Macron took similar steps. If we act now, and act decisively, we can stem the rising waters before our defences are breached.
