Thank you for your answer, Minister, and it's a positive reply, I think. I think that it's correct to use every tool in the toolbox and to call upon the army and the volunteer army that you talked about as well. I think it's welcome, and, of course, it's good news that we've got that supply as well.

But there's one area I would like to pick up, and this is, again, about walk-in centres for booster vaccinations. I raised this with you yesterday, and you cited the JCVI advice that each and every age group should be worked through in order, and you again claimed that it would be a free-for-all. Now, I think perhaps there's been a misunderstanding about what a walk-in centre is and how it operates. NHS England's advice is that letters, text messages and e-mails are automatically sent to those who need a booster, which can then be taken to the walk-in centre. And if you don't get one, then you can ask your GP. So, no letter, no jab. So, this is in order of the correct approach and taken in terms of need, but it also means those who are to receive the booster being able to do so as quickly as possible and as easy as possible for them. 

We're now at the point where the new variant has been, of course, identified in the UK, and I would say we must boost the booster programme. And the BMA this morning said that, 'If they want us to be involved'—talking about you—'If they want us to be involved in the COVID booster campaign, then, of course, something has to give.' So, to ensure that we have significant uptake of the booster, it's clear that we need to use every tool at our disposal. So, with GPs overstretched beyond their limits, can I ask you now to reconsider your rejection of walk-in centres as a means to support the booster jab roll-out?
