Llywydd, the rule of six I don't think is very difficult to follow. What we know is that coronavirus is being passed by people meeting inside each other's houses. That is what lies behind the transmission in Caerphilly. That is what lies behind the transmission in many parts of England. And in order to try to bring the position back under control, what we are proposing in Wales is that no more than six people should meet indoors at any one time; it limits the chain of transmission. It really is as simple as that. And when chains of transmission are driving up figures of people suffering from coronavirus in significant parts of Wales, and doing so quite alarmingly, then it is very important that the Government act to bring that back under control.

We have a more liberal regime here in Wales than elsewhere because four households are able to form a single extended household, and that itself provides an umbrella which helps to disrupt chains of transmission, but no more than six of those people should meet at any one time. We will allow primary school aged children to be part of that household beyond the six because of the evidence that those children don't suffer from coronavirus and don't transmit coronavirus in the way that adults do. It's a proportionate attempt to try not to interfere in people's freedoms more than the minimum necessary, but to do the minimum necessary in order to address the escalating numbers of coronavirus that we see in too many parts of Wales. 

As far as face coverings are concerned, in our local lockdown plan, again published in the middle of August, Llywydd, we said that if the circulation of the virus in Wales moved beyond a certain threshold, we would revisit our advice on face coverings. At the end of last week, the rate in Wales went to 20 per 100,000 of the population, and has remained above 20 ever since. Twenty is the figure we use to identify foreign countries where if you've been abroad and you have to return to the United Kingdom, you have to self-isolate. It seemed to me to be again a proportionate way of marking that unfortunate threshold that we should ask people in Wales to do that marginal thing, because when you get to circulation of the virus at that level, marginal bits of help that assist us all in keeping it under control and driving it down become worthwhile.
