Well, First Minister, I think it is important that we do see the evidence, because this policy has indeed changed. It's important that the Welsh Government is open and transparent on these matters because the public have a right to know what evidence has been used when a policy changes.

Now, moving on, First Minister, I'm pleased to see that the Isle of Wight is now preparing to trial a phone app that will track COVID-19 infections. First Minister, this may be an area that the Welsh Government can work on with the UK Government so that Wales can also be at the forefront of these technological developments. Whilst, of course, there are data issues on how it could be shared in Wales, this type of contact tracing could be of huge benefit to us here in Wales. Can you therefore confirm that Wales is willing to be part of this process, and that your officials are working with their counterparts in England to see how we could use this technology here in Wales? And will you commit to publishing the latest guidance that the Welsh Government receives on this issue, so that we can track and trace the Welsh Government's progress in this area?
