Diolch, Llywydd. First Minister, from 6 July, households in Wales have been permitted to join together to form an extended support bubble to enable families to reunite, meaning that people can form one extended household and meet indoors. That move was welcomed by many across Wales who, after months of being unable to see their loved ones, were finally able to spend some time with their families and with their friends. Given the pace at which so many changes are now being made, which now result in more and more people interacting with each other in outdoor and indoor spaces, perhaps it's time to consider the creation of further support bubbles, therefore. First Minister, can you tell us what scientific evidence is the Welsh Government using to underpin its policy on social bubbles? And can you also tell us what consideration the Welsh Government has given to further relaxing restrictions on this specific matter?
