Creating the 'Nightingale' hospitals is indeed an important step, and I do not downplay its significance.

But creating the building is the easiest and the least important part of the whole thing in many ways. The doctors, nurses, medical supplies and so on are nothing like so easy to get as converting a building. Yes, I know lots are coming out of retirement. But we are also losing a lot at the moment through necessary isolation.

The NHS staff have worked incredibly hard to get where we are, but sustaining that intensity over perhaps six months rather than two weeks is going to be a huge ask.

The buildings are one vital part of the jigsaw. But only one part.
